Local sim impovements (#4551) * Local sim impovements * Added support for running Capella and EIP-4844 simulations by downloading the correct version of Geth. * Added support for using Nimbus remote signer and Web3Signer. Use 2 out of 3 threshold signing configuration in the mainnet configuration and regular remote signing in the minimal one. * The local testnet simulation can now use a payload builder. This is currently not activated in CI due to lack of automated procedures for installing third-party relays or builders. You are adviced to use mergemock for now, but for most realistic results, we can create a simple builder based on the nimbus-eth1 codebase that will be able to propose transactions from the regular network mempool. * Start the simulation from a merged state. This would allow us to start removing pre-merge functionality such as the gossip subsciption logic. The commit also removes the merge-forcing hack installed after the TTD removal. * Consolidate all the tools used in the local simulation into a single `ncli_testnet` binary.

Shared validator pubkey (#5883) This PR allows sharing the pubkey data between validators by using a thread-local cache for pubkey data, netting about a 400mb mem usage reduction on holesky due to us keeping 3 permanent + several ephemeral state copies in memory at all times and each state copy holding a full validator. The PR also introduces a hash cache for the key which gives ~14% speedup for a full state `hash_tree_root` - the key makes up for a large part of the `Validator` htr time. Finally, the time it takes to copy a state goes down as well from ~80m ms to ~60, for reasons similar to htr. We use a `ptr` even if a `ref` could in theory have been used - there is not much practical benefit to a `ref` (given it's mutable) while a `ptr` is cheaper and easier to copy (when copying temporary states). We could go further and cache a cooked pubkey but it turns out this is quite intrusive - in all the relevant places, we're already using a cooked key from the immutable validator data so there are no immediate performance gains of doing so while managing the compressed -> cooked key mapping would become more difficult - something for a future PR perhaps.

Implement split preset/config support (#2710) * Implement split preset/config support This is the initial bulk refactor to introduce runtime config values in a number of places, somewhat replacing the existing mechanism of loading network metadata. It still needs more work, this is the initial refactor that introduces runtime configuration in some of the places that need it. The PR changes the way presets and constants work, to match the spec. In particular, a "preset" now refers to the compile-time configuration while a "cfg" or "RuntimeConfig" is the dynamic part. A single binary can support either mainnet or minimal, but not both. Support for other presets has been removed completely (can be readded, in case there's need). There's a number of outstanding tasks: * `SECONDS_PER_SLOT` still needs fixing * loading custom runtime configs needs redoing * checking constants against YAML file * yeerongpilly support `build/nimbus_beacon_node --network=yeerongpilly --discv5:no --log-level=DEBUG` * load fork epoch from config * fix fork digest sent in status * nicer error string for request failures * fix tools * one more * fixup * fixup * fixup * use "standard" network definition folder in local testnet Files are loaded from their standard locations, including genesis etc, to conform to the format used in the `eth2-networks` repo. * fix launch scripts, allow unknown config values * fix base config of rest test * cleanups * bundle mainnet config using common loader * fix spec links and names * only include supported preset in binary * drop yeerongpilly, add altair-devnet-0, support boot_enr.yaml

Implement split preset/config support (#2710) * Implement split preset/config support This is the initial bulk refactor to introduce runtime config values in a number of places, somewhat replacing the existing mechanism of loading network metadata. It still needs more work, this is the initial refactor that introduces runtime configuration in some of the places that need it. The PR changes the way presets and constants work, to match the spec. In particular, a "preset" now refers to the compile-time configuration while a "cfg" or "RuntimeConfig" is the dynamic part. A single binary can support either mainnet or minimal, but not both. Support for other presets has been removed completely (can be readded, in case there's need). There's a number of outstanding tasks: * `SECONDS_PER_SLOT` still needs fixing * loading custom runtime configs needs redoing * checking constants against YAML file * yeerongpilly support `build/nimbus_beacon_node --network=yeerongpilly --discv5:no --log-level=DEBUG` * load fork epoch from config * fix fork digest sent in status * nicer error string for request failures * fix tools * one more * fixup * fixup * fixup * use "standard" network definition folder in local testnet Files are loaded from their standard locations, including genesis etc, to conform to the format used in the `eth2-networks` repo. * fix launch scripts, allow unknown config values * fix base config of rest test * cleanups * bundle mainnet config using common loader * fix spec links and names * only include supported preset in binary * drop yeerongpilly, add altair-devnet-0, support boot_enr.yaml

Implement split preset/config support (#2710) * Implement split preset/config support This is the initial bulk refactor to introduce runtime config values in a number of places, somewhat replacing the existing mechanism of loading network metadata. It still needs more work, this is the initial refactor that introduces runtime configuration in some of the places that need it. The PR changes the way presets and constants work, to match the spec. In particular, a "preset" now refers to the compile-time configuration while a "cfg" or "RuntimeConfig" is the dynamic part. A single binary can support either mainnet or minimal, but not both. Support for other presets has been removed completely (can be readded, in case there's need). There's a number of outstanding tasks: * `SECONDS_PER_SLOT` still needs fixing * loading custom runtime configs needs redoing * checking constants against YAML file * yeerongpilly support `build/nimbus_beacon_node --network=yeerongpilly --discv5:no --log-level=DEBUG` * load fork epoch from config * fix fork digest sent in status * nicer error string for request failures * fix tools * one more * fixup * fixup * fixup * use "standard" network definition folder in local testnet Files are loaded from their standard locations, including genesis etc, to conform to the format used in the `eth2-networks` repo. * fix launch scripts, allow unknown config values * fix base config of rest test * cleanups * bundle mainnet config using common loader * fix spec links and names * only include supported preset in binary * drop yeerongpilly, add altair-devnet-0, support boot_enr.yaml

time: spring cleaning (#3262) Time in the beacon chain is expressed relative to the genesis time - this PR creates a `beacon_time` module that collects helpers and utilities for dealing the time units - the new module does not deal with actual wall time (that's remains in `beacon_clock`). Collecting the time related stuff in one place makes it easier to find, avoids some circular imports and allows more easily identifying the code actually needs wall time to operate. * move genesis-time-related functionality into `spec/beacon_time` * avoid using `chronos.Duration` for time differences - it does not support negative values (such as when something happens earlier than it should) * saturate conversions between `FAR_FUTURE_XXX`, so as to avoid overflows * fix delay reporting in validator client so it uses the expected deadline of the slot, not "closest wall slot" * simplify looping over the slots of an epoch * `compute_start_slot_at_epoch` -> `start_slot` * `compute_epoch_at_slot` -> `epoch` A follow-up PR will (likely) introduce saturating arithmetic for the time units - this is merely code moves, renames and fixing of small bugs.

Collecting the time related stuff in one place makes it easier to find, avoids some circular imports and allows more easily identifying the code actually needs wall time to operate. * move genesis-time-related functionality into `spec/beacon_time` * avoid using `chronos.Duration` for time differences - it does not support negative values (such as when something happens earlier than it should) * saturate conversions between `FAR_FUTURE_XXX`, so as to avoid overflows * fix delay reporting in validator client so it uses the expected deadline of the slot, not "closest wall slot" * simplify looping over the slots of an epoch * `compute_start_slot_at_epoch` -> `start_slot` * `compute_epoch_at_slot` -> `epoch` A follow-up PR will (likely) introduce saturating arithmetic for the time units - this is merely code moves, renames and fixing of small bugs.

Because accounting is done somewhat differently, the PR uses a fork-specific object to extrct the information in order to make the cost on the spec side low. * RewardInfo -> EpochInfo, ForkedEpochInfo * use array for computing new sync committee * avoid repeated total active balance computations in block processing * simplify proposer index check * simplify epoch transition tests * pre-compute base increment and reuse in epoch processing, and a few other small optimizations This PR introduces the type and does the heavy lifting in terms of refactoring - the tools that use the accounting will need separate PR:s (as well as refinements to the exportred information)
