John Khvatov eae49ff598 Perform L0 compaction before creating new image layers (#5950)
If there are too many L0 layers before compaction, the compaction
process becomes slow because of slow `Timeline::get`. As a result of the
slowdown, the pageserver will generate even more L0 layers for the next
iteration, further exacerbating the slow performance.

Change to perform L0 -> L1 compaction before creating new images. The
simple change speeds up compaction time and `Timeline::get` to 5x.
`Timeline::get` is faster on top of L1 layers.
