[CRD iOS] Ignore touch event when the touch point is out of the canvas in direct input mode

Previously if the user taps outside the bounds of the desktop canvas,
GestureInterpreter will still attempt to inject the out-of-bound mouse event
and show the touch feedback. The mouse event will be clamped back to the edge
of the desktop (e.g. (50, -100) => (50, 0)).

The Android client will ignore out-of-bound touch inputs in touch mode. This
CL does the same thing for iOS client.
