Chad Austin e419dd2799 remove the reference-counting overhead from DurationScope
Summary:
DurationScope has a pair of atomic reference count operations at the
beginning and end of every recorded duration. To avoid that overhead,
reference EdenStats with RefPtr and, in production EdenFS, store a
global, unowned EdenStats object.

This gives us the benefits of explicit dependencies and no global
state in tests, while avoiding atomic RMWs in the release build.
