storcon: add tenant_timeline_locate handler (#12203)

Browse Source 
## Problem
Compatibility tests may be run against a compatibility snapshot
generated with `--timelines-onto-safekeepers=false`. We need to start
the compute without a generation (or with 0 generation) if the timeline
is not storcon-managed, otherwise the compute will hang.

This handler is needed to check if the timeline is storcon-managed.
It's also needed for better test coverage of safekeeper migration code.

- Relates to https://github.com/neondatabase/neon/pull/11712

## Summary of changes
- Implement `tenant_timeline_locate` handler in storcon to get
safekeeper info from storcon's DB
