feat(interrupts): trigger SRI if vCPU waiting

Use the `sri-policy` option from the parititon
manifest SRI_POLICY_SEC_INT_WAITING.

If the target vCPU is in the waiting state, the
SPMC will trigger the SRI for the NWd at the next
world switch back.

Still missing the change to FFA_NOTIFICATION_INFO_GET.
