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.
