According to the virtio iommu spec (section 5.13.6.6), all mappings
within the entire range from virt_start to virt_end in an unmap
request must be removed. This change adds this functionality,
iterating through all mappings that fall within an unmap request
for that domain and removing them.

Current instruction emulator can only decode x86 instructions. Thus,
restrict the exit handling for just x86 guests.

APIC controller is only available on x86 machine. ARM uses a different
interrupt controller so those exit messages won't happen for ARM guests.

MSR and CPUID are limited to x86 architecture so, reduce the visbility
of these two members inside struct MshvVcpu to just x86 architecture.

A deadlock can happen from the destination VM of live upgrade or
migration due to waiting on paused device worker threads. For example,
when a serialization error happens after the `DeviceManager` struct is
restored (where all virtio device worker threads are spawned but in
paused/parked state), a deadlock will happen from
`DeviceManager::drop()`, as it blocks for waiting worker threads to
join.
This patch ensures that we wake up all device (mostly virtio) worker
threads before we block for them to join.

Current version can't boot a SNP guest while using
more than one VCPU. It turns out that there is an
issue in the Snp AP creation process. We should be writing
to Software exitinfo1 instead of exitinfo2. This patch fixes
the issue and we can boot multi vcpu SNP guest.
