Introduce Fiber::Scheduler#blocking_operation_wait. (#12016) 
Redirect `rb_nogvl` blocking operations to the fiber scheduler if possible
to prevent stalling the event loop.

Revert "Introduce Fiber Scheduler blocking_region hook. (#11963)" (#12013) 
This reverts some of commit 87fb44dff6409a19d12052cf0fc07ba80a4c45ac.

We will rename and propose a slightly different interface.

Fixed method names in exception messages 
These methods are not !-suffixed, and the messages were very
confusing.

Wake up join list within thread EC context. (#4471) 
* Wake up join list within thread EC context.

* Consume items from join list so that they are not re-executed.

If `rb_fiber_scheduler_unblock` raises an exception, it can result in a
segfault if `rb_threadptr_join_list_wakeup` is not within a valid EC. This
change moves `rb_threadptr_join_list_wakeup` into the thread's top level EC
which initially caused an infinite loop because on exception will retry. We
explicitly remove items from the thread's join list to avoid this situation.

* Verify the required scheduler interface.

* Test several scheduler hooks methods with broken `unblock` implementation.

178c1b0922 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]
