Move InputEventReceiver tracing to native code

InputEventReceiver.dispatchInputEvent is called with relatively
high frequency. Even when guarding the associated trace call and
string creation, it was showing up as a significant source of
StringBuilder and JNI overhead for some common traced scenarios.

Move the trace calls into native where `dispatchInputEvent` is
invoked. MotionEvent itself is backed by native data structures, so
associated member field queries are even cheaper when we do this
tracing natively.
