Description

We don't have a mutex destruction API. Now that we allow "complete" arena destruction, there are locations that we call the OS-appropriate mutex-init function on, but never mutex destruction. This is fine most of the time, but can cause resource leaks on systems where mutex initialization requires resource allocation.

Research direction

Start by locating the OS-appropriate mutex initialization calls used during complete arena destruction and identify where matching cleanup is missing. Define and add the mutex destruction API for those paths, then verify that every initialized mutex is destroyed on systems where initialization allocates resources.
