Dmitrii Kovalkov 136eaeb74a pageserver: basebackup cache (hackathon project) (#11989) ...

## Problem
Basebackup cache is on the hot path of compute startup and is generated
on every request (may be slow).

- Issue: https://github.com/neondatabase/cloud/issues/29353

## Summary of changes
- Add `BasebackupCache` which stores basebackups on local disk.
- Basebackup prepare requests are triggered by
`XLOG_CHECKPOINT_SHUTDOWN` records in the log.
- Limit the size of the cache by number of entries.
- Add `basebackup_cache_enabled` feature flag to TenantConfig.
- Write tests for the cache

## Not implemented yet
- Limit the size of the cache by total size in bytes
