accelerate EL sync with LC with `--sync-light-client` (#4041) 
When the BN-embedded LC makes sync progress, pass the corresponding
execution block hash to the EL via `engine_forkchoiceUpdatedV1`.
This allows the EL to sync to wall slot while the chain DAG is behind.
Renamed `--light-client` to `--sync-light-client` for clarity, and
`--light-client-trusted-block-root` to `--trusted-block-root` for
consistency with `nimbus_light_client`.

Note that this does not work well in practice at this time:
- Geth sticks to the optimistic sync:
  "Ignoring payload while snap syncing" (when passing the LC head)
  "Forkchoice requested unknown head" (when updating to LC head)
- Nethermind syncs to LC head but does not report ancestors as VALID,
  so the main forward sync is still stuck in optimistic mode:
  "Pre-pivot block, ignored and returned Syncing"

To aid EL client teams in fixing those issues, having this available
as a hidden option is still useful.
