hv: vcpu: Move vcpu common parts under common/vcpu.h (data structure)

Browse Source 
This commit cleans up struct acrn_vcpu. vcpu API cleanup will be in
future patch series.

Create a common vcpu.h hosting struct acrn_vcpu, and move some x86
specific members of struct acrn_vcpu into struct acrn_vcpu_arch. These
members includes:

reg_cached
reg_updated
inst_ctxt

And pending_req is being moved from arch to common.

And the maximum number of events (i.e., VCPU_EVENT_NUM) are being
replaced by MAX_VCPU_EVENT_NUM.

To avoid circular dependency, some in-header helpers are moved into
vcpu.c with only prototypes being declared inside header.
