[#12221] feat(iceberg): Add durable table delete lifecycle

[nevzheng]

What changes were proposed in this pull request?

This is Stack 20.1 of 3 and depends on #12223.

• Add the Iceberg REST soft-delete coordinator and configuration.
• When soft delete is enabled, replace the physical request-thread drop with one relational transaction that:
  • locks the exact live table_meta row by immutable table_id with SELECT ... FOR UPDATE;
  • inserts a minimal active deletion action (deletion_id, state, retention_expires_at, purge_job_id); and
  • stamps deleted_at and the same deletion_id on the locked row using its current schema, name, and metadata version.
• Keep table identity, name, version, ownership, and related metadata on the existing immutable table_id; the action does not duplicate them.
• Reserve retained names for create/register and hide retained roots from ordinary table operations.
• Treat a repeated DELETE of the already-retained name as successful.
• Preserve the existing DELETE paths when soft delete is disabled.

This layer intentionally does not add terminal restore receipts, copied identity fields, action revisions, or a deletion-audit table. Existing entity change events remain the cache-propagation mechanism.

Why are the changes needed?

This establishes the durable logical-delete boundary used by deleted-table reads, UNDROP, and a later asynchronous purge implementation without introducing a request-thread saga.

Related: #12221

Does this PR introduce any user-facing change?

Yes. When Iceberg REST soft deletion is enabled, DELETE retains and hides the existing table row and reserves its name. When it is disabled, existing behavior is unchanged.

How was this patch tested?

Added cross-backend relational lifecycle tests plus configuration, authorization, REST DELETE, dispatcher, name-reservation, retry, locked-current-version, and outer-transaction rollback tests. The focused Core and Iceberg REST Server suites pass.
