kvm_host: unify VM_STAT and VCPU_STAT definitions in a single place
The macros VM_STAT and VCPU_STAT are redundantly implemented in multiple
files, each used by a different architecure to initialize the debugfs
entries for statistics. Since they all have the same purpose, they can be
unified in a single common definition in include/linux/kvm_host.h
