Erik Grinaker 06090bbccd pageserver: log critical error on ClearVmBits for unknown pages (#10634)
## Problem

In #9895, we fixed some issues where `ClearVmBits` were broadcast to all
shards, even those not owning the VM relation. As part of that, we found
some ancient code from #1417, which discarded spurious incorrect
`ClearVmBits` records for pages outside of the VM relation. We added
observability in #9911 to see how often this actually happens in the
wild.

After two months, we have not seen this happen once in production or
staging. However, out of caution, we don't want a hard error and break
WAL ingestion.

Resolves #10067.

## Summary of changes

Log a critical error when ingesting `ClearVmBits` for unknown VM
relations or pages.
