compositor: Make input event handling per-WebView (#35716)

Browse source 
This is another step in the move to having a per-WebView renderer. In
this step event handling is made per-WebView. Most events sent to Servo
are sent via the WebView API already, so this just moves more event
handling code to the per-WebView render portion of the compositor.

- ServoRenderer is given shared ownership and interior mutability as
  it is now shared among all WebView(Renderers).
- Some messages coming from other parts of Servo must now carry a
  WebViewId as well so that they can be associated with a particular
  WebView.
- There needs to be some reorganization of `ServoRenderer` in order to
  avoid issues with double borrow of `RefCells`.
