This is a step with multiple intentions:
* Be correct.
* Unlock tests that are blocking @anholt.
* Ease the transition to typed arrays once the changes by @Ms2ger start rolling
in, since I expect the amount of test expectations to update to be
non-trivial.
Send touch events to root pipeline, and allow forwarding to iframes.
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.

IFrame elements now manage FrameIds rather than the constellation.
<!-- Please describe your changes on the following line: -->
This PR stores the FrameId as well as the PipelineId in an html iframe. The iframes are now responsible for creating frame ids, not the constellation.
This is the first step in fixing #633, because it means we know the frame id of each script thread when it is created. It also means we can share the frame id, for example using it in the debugger.
