This trades quite a bit of complicated code in Servo for few more
messages and a significant performance improvement. In particular,
WebRender can search the entire display list at once instead of
ping-ponging down the pipeline tree. This allows us to send mouse
events to the correct pipeline immediately.

This patch fixes a couple of issues in the compositor:
1) Remove the delayed composition code. Previously, this would schedule
a composite for 12ms in the future. This doesn't really make any sense
with WR. There's no point in doing a composite unless WR has provided
a new frame to be drawn. This fixes issues in several benchmarks where
we were doing multiple composite / renders per rAF, which is a waste
of CPU time. This *does* make the framerate slower in some cases (such
as a slow rAF callback) but it's more correct - otherwise we were just
compositing the same frame multiple times for no real benefit.
2) Inform the window of the current animation state of the compositor.
Specifically, if an animation (or rAF) is currently active, the
window system switches to use event polling, and does not block on
the OS-level event loop. In the case of active animation, we just
assume that we want to be running as the vsync interval and not
blocking. This means the compositor thread only sleeps on vsync
during animation, which reduces OS scheduling and results in much
smoother animation.

This removes paint threads, rust-layers dependency, and changes
optional webrender types to be required.
The use_webrender option has been removed, however I've left
the "-w" command line option in place for now so that wpt
runner can continue to pass that. Once it's removed from there
we can also remove the -w option.
Once this stage is complete, it should be fine to change the
display list building code to generate webrender display
lists directly and avoid the conversion step.

Previously, the flow for ticking animations was:
Compositor -> Constellation -> Layout -> Script
However, this means that the compositor <-> layout messages can thrash, meaning layout thread is very rarely idle.
This means that the script thread (which joins on the layout thread during reflow) was unable to execute and run rAF callbacks.
With this change, the flow is now:
Compositor -> Constellation -> Script (when rAF is active).
Compositor -> Constellation -> Layout (when transitions / animations are active and no rAF is present).
This makes rAF based animation *much* smoother.

Instead, schedule a delayed composite after each frame of an animation.
The previous code would cause jank, because the following sequence
frequently occurred:
1. The page uses `requestAnimationFrame()` to request a frame.
2. The compositor receives the message, schedules a composite,
dispatches the rAF message to the script thread, composites, and goes to
sleep waiting for vblank (frame 1).
3. The script makes a change and sends it through the pipeline.
Eventually it gets painted and is sent to the compositor, but the
compositor is sleeping.
4. The compositor wakes up, sees the new painted content, page flips,
and goes to sleep (frame 2). Repeat from step 1.
The problem is that we have two composition frames, not just one. This
halves Web apps' framerate!
This commit fixes the problem by scheduling the composite in step 2 to
12 ms in the future. We already have this delayed-composition
functionality in the form of the scrolling timer, which I repurposed and
renamed to the "delayed composition timer" for this task. This change
gives the page 12 ms to prepare the frame, which seems to usually be
enough, especially with WebRender.
Note that simply removing the scheduled composite after rAF is not the
correct solution. If this is done, then pages that call rAF and don't
modify the page won't receive future rAFs, since the compositor will be
sleeping and won't be notified of vblank.
Fixes a bunch of jank in browser.html. The remaining jank seems to be a
problem with browser.html itself.

* Our layer system doesn't yet support zooming `<iframe mozbrowser>` separately, so this can only zoom the root window.
* There are some issues that cause some tiles to disappear while zooming. I hope this will be fixed by WebRender.
* Sorry this is mostly in one giant commit. I did the refactoring and adding new functionality in tandem, and didn't really end up with logical or compilable intermediate commits. Hopefully the new code is easier to read than the old stuff.
