Ensure that we don't report huge mouse movement deltas for mouse enter and leave events.

The movement deltas are supposed to be fixed by the RWHVA::ModifyEventMovementAndCoords function.
However this function does not do the right thing because it checks the WebMouseEvent structure for a
mouse enter or leave event. The WebMouseEvent structure never sees a mouse enter or leave event as they
are converted to a mouse move event with the cursor position as the location.

Fixes as below:-
1. Pass the ui::MouseEvent structure to the RWHVA::ModifyEventMovementAndCoords function and use this
   to check if the mouse event is a mouse enter or leave.
