Erik Grinaker ff298afb97 pageserver: add level for timeline layer metrics (#10563) ...

## Problem

We don't have good observability for per-timeline compaction debt,
specifically the number of delta layers in the frozen, L0, and L1
levels.

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

## Summary of changes

* Add a `level` label for `pageserver_layer_{count,size}` with values
`l0`, `l1`, and `frozen`.
* Track metrics for frozen layers.

There is already a `kind={delta,image}` label. `kind=image` is only
possible for `level=l1`.

We don't include the currently open ephemeral layer, only frozen layers.
There is always exactly 1 ephemeral layer, with a dynamic size which is
already tracked in `pageserver_timeline_ephemeral_bytes`.
