cpus: add handle_interrupt to the CpusAccel interface

kvm: uses the generic handler
qtest: uses the generic handler
whpx: changed to use the generic handler (identical implementation)
hax: changed to use the generic handler (identical implementation)
hvf: changed to use the generic handler (identical implementation)
tcg: adapt tcg-cpus to point to the tcg-specific handler
