+ Introduce xSemaphoreGenericGiveFromISR() as an optimisation when giving semaphores and mutexes from an interrupt.

Demo applications:
+ Update IntSemTest.c to provide more code coverage in xSemaphoreGenericGiveFromISR().
+ Ensure the MMU is turned on in the RZ IAR demo.  It was already on in the RZ ARM demo.
