Make Mutex per-Fiber instead of per-Thread
* Enables Mutex to be used as synchronization between multiple Fibers of the same Thread. * With a Fiber scheduler we can yield to another Fiber on contended Mutex#lock instead of blocking the entire thread. * This also makes the behavior of Mutex consistent across CRuby, JRuby and TruffleRuby. * [Feature #16792]
