virt: acrn: Introduce interrupt injection interfaces
ACRN userspace need to inject virtual interrupts into a User VM in
devices emulation.
HSM needs provide interfaces to do so.
Introduce following interrupt injection interfaces:
ioctl ACRN_IOCTL_SET_IRQLINE:
Pass data from userspace to the hypervisor, and inform the hypervisor
to inject a virtual IOAPIC GSI interrupt to a User VM.
ioctl ACRN_IOCTL_INJECT_MSI:
Pass data struct acrn_msi_entry from userspace to the hypervisor, and
inform the hypervisor to inject a virtual MSI to a User VM.
ioctl ACRN_IOCTL_VM_INTR_MONITOR:
Set a 4-Kbyte aligned shared page for statistics information of
interrupts of a User VM.
