score: Add _Thread_Get_interrupt_disable()

Remove _Thread_Acquire() and _Thread_Acquire_for_executing().  Add
utility functions for the default thread lock.   Use the default thread
lock for the RTEMS events.  There is no need to disable thread
dispatching and a Giant acquire in _Event_Timeout() since this was
already done by the caller.

Update #2273.
