Vlad Lazar 9957c6a9a0 pageserver: drop the layer map lock after planning reads (#7215) ...

## Problem
The vectored read path holds the layer map lock while visiting a
timeline.

## Summary of changes
* Rework the fringe order to hold `Layer` on `Arc<InMemoryLayer>`
handles instead of descriptions that are resolved by the layer map at
the time of read. Note that previously `get_values_reconstruct_data` was
implemented for the layer description which already knew the lsn range
for the read. Now it is implemented on the new `ReadableLayer` handle
and needs to get the lsn range as an argument.
* Drop the layer map lock after updating the fringe.
