feat(common): Detect when the cross-process lock has been dirtied.

This patch detects when the cross-process lock has been dirtied.

A new `CrossProcessLockResult` enum is introduced to simplify the
returned value of `try_lock_once` and `spin_lock`. It flattens the
previous `Result<Option<_>>` by providing 3 variants: `Clean`, `Dirty`
and `Unobtained`.
