refactor(interrupts): changes based on updated guidance

In anticipation of updated guidance for interrupt management based
on FF-A v1.1 EAC0 specification, changes are made to add helper
utilities to distinguish handling secure interrupt triggered while
executing in normal world vs secure world.

Moreover, a legacy design constraint has been removed. SPMC now
changes the state of the target SP to RUNNING upon resuming it
for handling a secure virtual interrupt.
