Andrew Rudenko acc075071d feat(compute_ctl): add periodic lease lsn requests for static computes (#7994) ...

Part of #7497

## Problem

Static computes pinned at some fix LSN could be created initially within
PITR interval but eventually go out it. To make sure that Static
computes are not affected by GC, we need to start using the LSN lease
API (introduced in #8084) in compute_ctl.

## Summary of changes

**compute_ctl**
- Spawn a thread for when a static compute starts to periodically ping
pageserver(s) to make LSN lease requests.
- Add `test_readonly_node_gc` to test if static compute can read all
pages without error.
  - (test will fail on main without the code change here)

**page_service**
- `wait_or_get_last_lsn` will now allow `request_lsn` less than
`latest_gc_cutoff_lsn` to proceed if there is a lease on `request_lsn`.
