make preset header comments consistent (#2905) Currently there is a mix of comment formats in the various preset files. Altair presets have a leading header line, Phase0 presets don't. Furthermore, the Altair `minimal` header refers to `mainnet` (#2710). Updated all of the header lines to match the spec.

# Mainnet preset - Phase0
update consensus spec ref URLs to v1.2.0 (#4164)

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

Support for Gnosis Chain (#3415) * Support for Gnosis Chain `make gnosis-chain-build` will build the Nimbus gnosis chain binary, stored in `build/nimbus_beacon_node_for_gnosis_chain`. `make gnosis-chain` will connect to the network. Other changes: * Restore compilation with -d:has_genesis_detection * Removed Makefile target related to testnet0 and testnet1 * Added more debug logging for failed peer handshakes * Report misconfigured builds which try to embed network metadata that is incompatible with the currently selected const preset. * Don't bundle network metadata in minimal builds, as they are not compatible
