Alex Chi Z.andChen Luo 3815e3b2b5 feat(pageserver): reduce lock contention in l0 compaction (#12360) ...

## Problem

L0 compaction currently holds the read lock for a long region while it
doesn't need to.

## Summary of changes

This patch reduces the one long contention region into 2 short ones:
gather the layers to compact at the beginning, and several short read
locks when querying the image coverage.
