hypervisor, vmm: move away from CpuId type

Browse Source 
CpuId is an alias type for the flexible array structure type over
CpuIdEntry. The type itself and the type of the element in the array
portion are tied to the underlying hypervisor.

Switch to using CpuIdEntry slice or vector directly. The construction of
CpuId type is left to hypervisors.

This allows us to decouple CpuIdEntry from hypervisors more easily.

No functional change intended.
