Refactoring WebContentsDelegate::ContentsMouseEvent.

It is now called for all mouse events, not just MOVED and EXITED
(matching its name). A new parameter |exited| was added for EXITED
events (like the existing |motion| parameter).

Rationale: I want to signal the fullscreen bubble on mouse events, and
this seemed a good place to do it except it wasn't receiving all mouse
events.
