core: spmc: handle non-secure interrupts

Add FFA_INTERRUPT and FFA_RUN support for signaling non-secure
interrupts and for resuming to the secure world. If a secure partition
is preempted by a non-secure interrupt OP-TEE saves the SP's state and
sends an FFA_INTERRUPT to the normal world. After handling the interrupt
the normal world should send an FFA_RUN to OP-TEE so it can continue
running the SP.
If OP-TEE is the active FF-A endpoint (i.e. it is running TAs) the
non-secure interrupts are signaled by the existing
OPTEE_FFA_YIELDING_CALL_RETURN_INTERRUPT message instead of
FFA_INTERRUPT.
