Subject: [PATCH v2 1/3] tools/perf: Move kvm-stat header file from conditional inclusion to common include section

Move kvm-stat header file to the common include section, and make the
definitions in the header file under the conditional inclusion 
`#ifdef HAVE_KVM_STAT_SUPPORT`.

This helps to define other perf kvm related function prototypes in
kvm-stat header file, which may not need kvm-stat support.
