EIP4844: Update cryptography API (#3038)
This commit changes the public API of the KZG library to the following high-level API:

```
- verify_kzg_proof()
- compute_aggregate_kzg_proof()
- verify_aggregate_kzg_proof()
- blob_to_kzg_commitment()
```

compared to the previous much more low-level API:

```
- compute_powers()
- matrix_lincomb()
- lincomb()
- bytes_to_bls_field()
- evaluate_polynomial_in_evaluation_form()
- verify_kzg_proof()
- compute_kzg_proof()
```

This means that all the cryptographic logic (including Fiat-Shamir) is now isolated and hidden in the KZG library and the `validator.md` file ends up being significantly simplified, only calling high-level KZG functions.

Some additional things that this commit does:

- Moves all EIP4844 cryptography into polynomial-commitments.md
- Improves the Fiat-Shamir stack by removing the need for SSZ and by introducing simple domain separators

Move `is_post_xxx` functions to new module
Moving the `is_post_xxx` functions to a separate module allows `genesis`
to also use them (cyclic import from `context` prevented this before).
This allows removing `FORKS_BEFORE_ALTAIR` and `FORKS_BEFORE_BELLATRIX`
constants and adding a more general `is_post_fork` function that needs
less maintenance. This then allows definition of `with_all_phases_from`
to streamline the implementation of the `with_xxx_and_later` decorators.

Pass blocks to LC data creation functions
Future light client protocol extensions may include data from the block
in addition to data from the state, e.g., `ExecutionPayloadHeader`.
To prepare for this, also pass the block to the corresponding functions.
In practice, blocks access is easier than historic state access, meaning
there are no practical limitations due to this change.

Update `remerkleable` to 0.1.25
`remerkleable` was updated to address potentially incorrect computation
of `hash_tree_root` against default-initialized `Vector` objects.
Switching to the fixed version.

Rename LC test check from `root` to `beacon_root`
Future light client tests will also incorporate execution payload data.
To avoid confusion, rename the current `root` check to `beacon_root`.
Doing this now, as #3066 already requires LC test runners to update.

Allow extending LC merkle proof tests
Currently, `test_single_merkle_proof` only supports `BeaconState` tests.
For future tests, different object classes are desirable. Update format
to allow testing other objects as well.

Etan Kissling 5b6eb8007a
Clarify where LC proofs are rooted
Add more detailed LC object documentation to explain that the various
merkle proofs are relative to the beacon block's state root.
Likewise, clarify that sync committees relate to the finalized header
(not to the optimistic header, which can be a period ahead).

Consistently use `compute_sync_committee_period_at_slot`
A few LC functions were not yet updated to use a more concise function
for computing sync committee period for a slot. Updating to that func.

Document how to derive fork context for LC gossip
For LC gossip, the documentation did not specify what slot number to use
for deriving the gossip objects. This missing documentation is now added
to document using `attested_header.slot`.

Consistent variable name in LC test
In light client tests, a variable is named `finality_header` but
everywhere else it is called `finalized_header`. Rename for consistency.
