Move Android jvmti.h header

...so that it can be used when building in AOSP. Previously this file
was only available under tools/vendor/google (see Change I53602847b).

jvmti.h is copied from the Android runtime:
http://android.googlesource.com/platform/art/+/25199ea87e/openjdkjvmti

jvmti.h is originally derived from OpenJDK. Copyright and license
information are available in the newly added LICENSE file.
