Populating these cpuid with default values so that
CLH can patch with topology information. Otherwise it gets
skipped while setting some topology information.

Certain VMEXITs can only happen for x86 guests, thus reduce the scope to
x86_64 at the compilation stage.

Create a partition frozen always, then unfreeze the partition
during boot phase or resume phase. We also freeze the
partition during pause event. Time is freeze during the
time between freeze and unfreeze.

Add Pause/Resume functions for VM trait. For KVM it
will be empty implementations. For MSHV it needs to freeze
and unfreeze the partition.

The list is gathered from going through various code paths in the code
base.
No functional change intended.

Per the KVM API document, that capability is only valid with in-kernel
irqchip that handles MSIs.
Through out the code base, there is no call to KVM_IOCTL_SIGNAL_MSI.

The contents of this crate may change and cause conflicts - re-exporting
the contents is unnecessary.

This is required as the VcpuFd::run and VcpuFd::set_immediate_exit
methods now take a &mut self. I explored alternative solutions:
1. Using RefCell for runtime interior mutability - the Vcpu trait is
Sync and it's not possible to use RefCell with types that are Sync.
2. Using UnsafeCell - the mutable reference nature of ::run and and
::set_kvm_immediate_exit was added for a reason so it unwise to
bypass this.
3. Adjusting the trait interface to expose the &mut self - this requires
an Arc<Mutex<>> around the hypervisor::vcpu::Vcpu object and was very
intrusive.

The members for {Io, Mmio}{Read, Write} are unused as instead exits of
those types are handled through the VmOps interface. Removing these is
also a prerequisite due to changes in the mutability of the
VcpuFd::run() method.

On Microsoft Hypervisor, we need to save/restore five
VP state components which are as follows:
1. Local APIC
2. Xsave
3. Synthetic Message Page
4. Synthetic Event Flags Page
5. Synthetic Timers
In the MSHV crate we created a single struct for all the
components and API to get/set the states.

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

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.

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.
