Fix PlayerView touch handling

Overriding onTouchEvent was causing multiple issues, and
appears to be unnecessary. Removing the override fixes:

1. StyledPlayerView accessibility issue where "hide player
   controls" actually toggled play/pause.
2. Delivery of events to a registered OnClickListener when
   useController is false.
3. Delivery of events to a registered OnLongClickListener
   in all configurations.
4. Incorrectly treating a sequence of touch events that
   exit the bounds of the view before ACTION_UP as a click,
   both for delivery to OnClickListener and for toggling
   the controls.

Note: After this change, control visibility will not be
toggled if the application developer explicitly sets the
view to be non-clickable. I think that's probably working
as intended though. It seems correct that a non-clickable
view would not respond to clicks.
