This PR adds the bulk verkle witness+proof production at the end of block
production. It reads all data from the tree in one swoop and produces
a verkle proof.

This is a performance improvement on the account-creation rollback code
required for the archive node to support verkle. It uses the utility
function `DeleteAtStem` to remove code and account data per-group
instead of doing it leaf by leaf.
It also fixes an index bug, as code is chunked in 31-byte chunks, so
comparing with the code size should use 31 as its stride.

The package `github.com/golang/protobuf/proto` is deprecated in favor
`google.golang.org/protobuf/proto`. We should update the codes to
recommended package.

This adds support for the Deneb beacon chain fork, and fork handling
in general, to the beacon chain light client implementation.

Since Go 1.22 has deprecated certain elliptic curve operations, this PR removes
references to the affected functions and replaces them with a custom implementation
in package crypto. This causes backwards-incompatible changes in some places.

Here we add a beacon chain light client for use by geth.
Geth can now be configured to run against a beacon chain API endpoint,
without pointing a CL to it. To set this up, use the `--beacon.api` flag. Information
provided by the beacon chain is verified, i.e. geth does not blindly trust the beacon
API endpoint in this mode. The root of trust are the beacon chain 'sync committees'.
The configured beacon API endpoint must provide light client data. At this time, only
Lodestar and Nimbus provide the necessary APIs.
There is also a standalone tool, cmd/blsync, which uses the beacon chain light client
to drive any EL implementation via its engine API.
