x86/hyperv: Expand definition of struct hv_vp_assist_page
The struct hv_vp_assist_page has 24 bytes which is defined as u64[3],
expand that to expose vtl_entry_reason, vtl_ret_x64rax and vtl_ret_x64rcx
field. vtl_entry_reason is updated by hypervisor for the entry reason as
to why the VTL was entered on the virtual processor.
Guest updates the vtl_ret_* fields to provide the register values to
restore on VTL return. The specific register values that are restored
which will be updated on vtl_ret_x64rax and vtl_ret_x64rcx.
Also added the missing fields for synthetic_time_unhalted_timer_expired,
virtualization_fault_information and intercept_message.
