feat(tvix/store): add new_temporary for all Sled services r/5934

This provides a service using /dev/shm, that's deleted once the
reference is dropped.

Refactor all tests to use these, which allows getting rid of most
TempDir usage in the tests.

The only place where we still use TempDir is in the importer tests,
which work on a filesystem path.
