HV_PAGE_SIZE is defined as a usize in mshv_bindings.
Remove the redefinition, and perform casts where necessary.

The 'NetConfig' may contain FDs which can't be serialized correctly, as
FDs can only be donated from another process via a Unix domain socket
with `SCM_RIGHTS`. To avoid false use of the serialized FDs, this patch
explicitly set 'NetConfig' FDs as invalid for (de)serialization.

Prefix field with an _ to indicate that this is intentionally unused.
This resolved a nightly compiler check issue due to the unusued field.

When restoring a VM, the VirtioPciCfgCapInfo struct is not properly
initialized. All fields are 0, including the offset where the
capabibility starts. Hence, when you read a PCI configuration register
in the range [0..length(VirtioPciCfgCap)] you get the value 0 instead of
the actual register contents.
Linux rescans the whole PCI bus when adding a new device. It reads the
values vendor_id and device_id for every device. Because these are
stored at offset 0 in pci configuration space, their value is 0 for
existing devices. As such, Linux considers that the devices have been
unplugged and it removes them from the system.
Fixes: #6265

Current MSHV emulator only works for x86 instruction decoder. So, let's
restrict its usage to x86.

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.
