9ce6c3b75c hypervisor, vmm: Feature guard KVM specific code 
There are some code base and function which are purely KVM specific for
now and we don't have those supports in mshv at the moment but we have plan
for the future. We are doing a feature guard with KVM. For example, KVM has
mp_state, cpu clock support,  which we don't have for mshv. In order to build
those code we are making the code base for KVM specific compilation.

a44d96c9cc hypervisor: emulator: switch to use vec in MockVMM 
The customized hashmap macro can't be lifted to common MockVMM code.
MockVMM only needs a collection to iterate over to get initial register
states. A vector is just as good as a hashmap.

Switch to use a vector to store initial register states. This allows us
to drop the hashmap macro everywhere.

ffaab46934 misc: Use a more relaxed memory model when possible 
When a total ordering between multiple atomic variables is not required
then use Ordering::Acquire with atomic loads and Ordering::Release with
atomic stores.

This will improve performance as this does not require a memory fence
on x86_64 which Ordering::SeqCst will use.

Add a comment to the code in the vCPU handling code where it operates on
multiple atomics to explain why Ordering::SeqCst is required.
