Alex Chi Z. c1be84197e feat(pageserver): preempt image layer generation if L0 piles up (#10572) ...

## Problem

Image layer generation could block L0 compactions for a long time.

## Summary of changes

* Refactored the return value of `create_image_layers_for_*` functions
to make it self-explainable.
* Preempt image layer generation in `Try` mode if L0 piles up.

Note that we might potentially run into a state that only the beginning
part of the keyspace gets image coverage. In that case, we either need
to implement something to prioritize some keyspaces with image coverage,
or tune the image_creation_threshold to ensure that the frequency of
image creation could keep up with L0 compaction.
