Remove an unnecessary synchronous full reflow.
We already reflow any nodes that are dirtied during any turn of the event loop. There is no reason to synchronously reflow the entire document, especially when we don't even modify it in this method.

Make webgl behave better with session history
This prevents the compositor from animating pages that are not actually visible, so pages using webgl do not needlessly impact the performance of the rest of the browser. Additionally, this fixes a problem that was alluded to in [this code](b5228c098b/src/draw_buffer.rs (L282-L285)), causing Servo to delete arbitrary resources when a GC occurred in content that used three.js.

Update WebIDL.py
I'm working on getting [attributes on types landed in upstream webidl](https://bugzilla.mozilla.org/show_bug.cgi?id=1359269). In preparation for that, I'd like to update WebIDL.py and deal with all the conflicts first so that updating for that bug is easier.
(This PR doesn't need to be reviewed and landed right now, I can just roll it into the PR for implementing attributes on types, but I suspect it would be easier to land this first)
Probably should squash before landing, the steps are separated out for ease of review.
