hv: nested: implement the framework for VMX MSR emulation

Browse Source 
Define LIST_OF_VMX_MSRS which includes a list of MSRs that are visible to
L1 guests if nested virtualization is enabled.
- If CONFIG_NVMX_ENABLED is set, these MSRs are included in
  emulated_guest_msrs[].
- otherwise, they are included in unsupported_msrs[].

In this way we can take advantage of the existing infrastructure to
emulate these MSRs.
