Erik Grinaker 6a2afa0c02 pageserver: add per-timeline read amp histogram (#10566) ...

## Problem

We don't have per-timeline observability for read amplification.

Touches https://github.com/neondatabase/cloud/issues/23283.

## Summary of changes

Add a per-timeline `pageserver_layers_per_read` histogram.

NB: per-timeline histograms are expensive, but probably worth it in this
case.
