Send touch events to root pipeline, and allow forwarding to iframes.

Browse source 
Instead of letting the compositor try to find the correct scroll
layer for a touch event, switch touch events to work the same way
that mouse events do.

Touch events are now dispatched to the root pipeline, and then
forwarded to child iframes as required.
