John Spray 923974d4da safekeeper: don't un-evict timelines during snapshot API handler (#9428) ...

## Problem

When we use pull_timeline API on an evicted timeline, it gets downloaded
to serve the snapshot API request. That means that to evacuate all the
timelines from a node, the node needs enough disk space to download
partial segments from all timelines, which may not be physically the
case.

Closes: #8833 

## Summary of changes

- Add a "try" variant of acquiring a residence guard, that returns None
if the timeline is offloaded
- During snapshot API handler, take a different code path if the
timeline isn't resident, where we just read the checkpoint and don't try
to read any segments.
