Description

Schema change backfills can become too disruptive at scale, so let's disallow them for now. Same with initial scans.

Research direction

Start by locating the changefeedccl implementation and the handling for database-level feeds. Trace how schema change backfills and initial scans are configured, then inspect nearby tests. Done means database-level feeds default to both options being off and reject requests that enable them, with coverage for those cases.
