Erik Grinaker 8a8c656c06 pageserver: add LayerMap::watch_layer0_deltas() (#10470) ...

## Problem

For compaction backpressure, we need a mechanism to signal when
compaction has reduced the L0 delta layer count below the backpressure
threshold.

Extracted from #10405.

## Summary of changes

Add `LayerMap::watch_level0_deltas()` which returns a
`tokio::sync:⌚:Receiver` signalling the current L0 delta layer
count.
