hv: add API to get the vcpu mapped to specific pcpu.

Browse Source 
Per performance consideration, we don't flush vcpu context when doing
vcpu swithing (because it's only swithing between vcpu and idle).

But when enter S3, we need to call vmclear against all vcpus attached
to APs. We need to know which vcpu is attached with which pcpu.

This patch introduced API to get vcpu mapped to specific pcpu.
