tm27: Add TM27_INTERRUPT_VECTOR_ALTERNATIVE

Browse Source 
The TM27 support may define TM27_INTERRUPT_VECTOR_ALTERNATIVE to provide
an alternative software generated interrupt request which is raised by
_TM27_Raise_alternative() and cleared by _TM27_Clear_alternative().
Both functions shall return an RTEMS status code.  This interrupt vector
may be used to test the interrupt controller support on targets which do
not provide generic software generated interrupts.

Update #3716.
