Deny register writes if a vm_client subscribed to mov_to_msr or

Changes since V3:
 - Renamed MEM_ACCESS_FLAG_DENY to VM_EVENT_FLAG_DENY (and fixed
   the bit shift appropriately).
 - Moved the DENY vm_event response logic from p2m.c to newly
   added dedicated files for vm_event handling, as suggested
   by Tamas Lengyel.

This looks good to me. It will have to be rebased on staging once the other series is merged as couple things will conflict. If this series lands first however, the newly added asm/vm_event files lack the required license header.

With that:
