feat: add support for secure interrupt handling and completion

As per FF-A v1.1 spec, the conduit used by SPM to signal an interrupt
to S-EL1 Partition is vIRQ and/or ERET.

Depending on the execution state of the vCPU of the target SP,
FFA_INTERRUPT ABI and/or Interrupt ID can be used as parameters during
eret to the SP.

This patch adds support for secure interrupt handling in Cactus SP as
well as adds support for FFA_INTERRUPT ABI in the message loop.
