In Gloas, beacon blocks are imported into fork choice immediately - the payload envelope and data columns arrive
separately. KZG commitments moved from the column sidecar into the execution payload bid, so the existing
`DataAvailabilityChecker` (which assumes block and data are coupled) can't be used for Gloas.
* Introduced `PendingPayloadCache` to keep track of payload and data columns per block root.
* Added gossip column verification
* Added support for Gloas data column reconstruction
* Payload envelope verification simplified: removed `MaybeAvailableEnvelope`, `ExecutedEnvelope`, `EnvelopeImportData`
Not yet implemented (tracked with TODOs):
- Proper lookup sync for Gloas columns arriving before blocks
- Partial column merging for Gloas
- Moving `load_gloas_payload_bid` disk reads off the async runtime
- Backfill/range sync for Gloas
Based on @eserilev's PR and work in progress. See also #9202 for verification.

Gossip verify and cache bids and proposer preferences. This PR also ensures we subscribe to new fork topics one epoch early instead of two slots early. This is required for proposer preferences.

Emit `execution_payload_gossip` on successful gossip verification of an execution payload. This is done as last step inside the verification function.
