1fc6d50f3e misc: Make Bus::write() return an Option<Arc<Barrier>> 
This can be uses to indicate to the caller that it should wait on the
barrier before returning as there is some asynchronous activity
triggered by the write which requires the KVM exit to block until it's
completed.

This is useful for having vCPU thread wait for the VMM thread to proceed
to activate the virtio devices.

See #1863

8c85dd32fa hypervisor: Move msr and msr_data macro to arch/x86 
Currently these two macros(msr, msr_data) reside both on kvm and mshv
module. Definition is same for both module. Moving them to arch/x86
module eliminates redundancy and makes more sense.

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.
