Yuchen Liang 219e78f885 feat(pageserver): add an optional lease to the get_lsn_by_timestamp API (#8104) ...

Part of #7497, closes #8072.

## Problem

Currently the `get_lsn_by_timestamp` and branch creation pageserver APIs do not provide a pleasant client experience where the looked-up LSN might be GC-ed between the two API calls.

This PR attempts to prevent common races between GC and branch creation by making use of LSN leases provided in #8084. A lease can be optionally granted to a looked-up LSN. With the lease, GC will not touch layers needed to reconstruct all pages at this LSN for the duration of the lease.
