s390x/flic: introduce inject_airq callback
Let's introduce a specialized way to inject adapter interrupts that,
unlike the common interrupt injection method, allows to take the
characteristics of the adapter into account.
For adapters subject to AIS facility:
- for non-kvm case, we handle the suppression for a given ISC in QEMU.
- for kvm case, we pass adapter id to kvm to do airq injection.
Add add tracepoint for suppressed airq and suppressing airq.
