Summary

Ref T13490. Frequently, we know the symbolic name of a commit (like "master") but need the immutable identifier for it (the commit hash).

Provide a Ref and Query for doing this lookup.

Test Plan

Ran arc inspect symbol(...) with various symbols, saw appropriate resolutions, nulls, or errors.
