[ty] Teach `ty` the meaning of desperation (try ancestor `pyproject.toml`s as search-paths if module resolution fails) (#21745)
## Summary

This makes an importing file a required argument to module resolution,
and if the fast-path cached query fails to resolve the module, take the
slow-path uncached (could be cached if we want)
`desperately_resolve_module` which will walk up from the importing file
until it finds a `pyproject.toml` (arbitrary decision, we could try
every ancestor directory), at which point it takes one last desperate
attempt to use that directory as a search-path. We do not continue
walking up once we've found a `pyproject.toml` (arbitrary decision, we
could keep going up).

Running locally, this fixes every broken-for-workspace-reasons import in
pyx's workspace!

* Improves https://github.com/astral-sh/ty/issues/839

## Test Plan

The workspace tests see a huge improvement on most absolute imports.
