Expose an interrupt processing handler for a single hw engine. Refactor code to use this handler from the VF. This handler also caters for the MSI-X mode, where the hardware engines report interrupt source and status to the offset of engine instance zero (this usage will be introduced in upcoming MSI-X enabling series).
