MINOR: thread: add EXTRAS_LOCK so addons can name their locks

Provide an unconditional EXTRAS_LOCK label so addons can name their
locks using the existing lock debugging and statistics infrastructure.
This avoids adding addon-specific lock labels or build-option guards to
the core enum. Report the label as EXTRAS in lock statistics.
