John Spray e2d89f7991 pageserver: prioritize secondary downloads to get most recent layers first, except l0s (#8729) ...

## Problem

When a secondary location is trying to catch up while a tenant is
receiving new writes, it can become quite wasteful:
- Downloading L0s which are soon destroyed by compaction to L1s
- Downloading older layer files which are soon made irrelevant when
covered by image layers.

## Summary of changes

Sort the layer files in the heatmap:
- L0 layers are the lowest priority
- Other layers are sorted to download the highest LSNs first.
