pageserver: add disk consistent and remote lsn metrics (#10005)

Browse Source 
## Problem

There's no metrics for disk consistent LSN and remote LSN. This stuff is
useful when looking at ingest performance.

## Summary of changes

Two per timeline metrics are added: `pageserver_disk_consistent_lsn` and
`pageserver_projected_remote_consistent_lsn`. I went for the projected
remote lsn instead of the visible one
because that more closely matches remote storage write tput. Ideally we
would have both, but these metrics are expensive.
