Use input token in PointerCaptureRequest
Instead of sending boolean to indicate the capture state,
InputDispatcher now sends an input window token that requests a
pointer capture, or nullptr otherwise.
This is useful for some InputReader implementations.
Also, this token can be used to verify if a pointer capture changed
event from a reader is valid.
