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.
