jni: Switch to @FastNative for all JNI functions. Deprecate !bang JNI.

Switches all (248) methods that previously used !bang JNI in art/libcore
to all use @FastNative.

Also deprecate !bang JNI since nothing in Android seems to (or should
be) using it anymore.

This measures to be a 3% startup time improvement in system_server.

Test: make test-art-host
