Alex Chi Z. 4f7b2cdd4f feat(pageserver): gc-compaction result verification (#11515) ...

## Problem

Part of #9114 

There was a debug-mode verification mode that verifies at every
retain_lsn. However, the code was tangled within the actual history
generation itself and it's hard to reason about correctness. This patch
adds a separate post-verification of the gc-compaction result that redos
logs at every retain_lsn and every record above the GC horizon. This
ensures that all key history we produce with gc-compaction is readable,
and if there're read errors after gc-compaction, it can only be
read-path errors instead of gc-compaction bugs.

## Summary of changes

* Add gc_compaction_verification flag, default to true.
* Implement a post-verification process.
