John Spray 6014f15157 pageserver: suppress noisy "layer became visible" logs (#9064) ...

## Problem

When layer visibility was added, an info log was included for the
situation where actual access to a layer disagrees with the visibility
calculation. This situation is safe, but I was interested in seeing when
it happens.

The log is pretty high volume, so this PR refines it to fire less often.

## Summary of changes

- For cases where accessing non-visible layers is normal, don't log at
all.
- Extend a unit test to increase confidence that the updates to
visibility on access are working as expected
- During compaction, only call the visibility calculation routine if
some image layers were created: previously, frequent calls resulted in
the visibility of layers getting reset every time we passed through
create_image_layers.
