Alex Chi Z. 0950866fa8 fix(pageserver): limit num of delta layers for l0 compaction (#8391) ...

## Problem

close https://github.com/neondatabase/neon/issues/8389

## Summary of changes

A quick mitigation for tenants with fast writes. We compact at most 60
delta layers at a time, expecting a memory footprint of 15GB. We will
pick the oldest 60 L0 layers.

This should be a relatively safe change so no test is added. Question is
whether to make this parameter configurable via tenant config.
