Gloas Column and Blob variants and deprecating full blob support

[eserilev]

Issue Addressed

Data column sidecar is changing in Gloas
data columns: https://github.com/ethereum/consensus-specs/blob/master/specs/gloas/p2p-interface.md#modified-datacolumnsidecar

Since we're now in Fulu, we can deprecate blob support for

• lookup sync
• get blobs v1
• gossip

However we still need to support blobs for

• reconstructing blobs from columns
• backfill sync (and technically range sync, because if we support blobs for backfill it would be hard to deprecate support for blobs in range sync)

I think this PR should go in after our 8.1 release and 8.1 should be the last release where we have full blob support

TODOs:

• Add p2p verification logic for Gloas columns
• Ensure we have adequate test coverage. Many blob tests were replacted with column tests
• Fix ef tests. Theres some blob fork choice tests that I think we should just delete.
• PR self review, and potentially clean things up further
