This fixes the assertion, though not the test-case, but now I can debug the
test-case and also land it as failing for now.
What was happening is that we had two ASRs (for the canvas and for the <body>),
and we were creating scroll data for the CompositorHitTestInfo of the <body>
(which obviously didn't have any ancestor transform) and for the
nsDisplayTransform in the backface for which HasPerspective returns true for,
but which already had an ancestor transform for the frame for which
ChildrenHavePerspective returns true.
It may be less risky to force it for both, but this doesn't make anything fail.

Previously, WebRender was getting a rectangle for reference frames
and stacking contexts, and it had to carefully treat the origin of this rectange:
- by offseting all the items in a stacking context
- by negatively compensating the sticky frame scroll port according to the
parent reference frame origin
With this change, we stop providing any non-zero origins. Instead we accomplish
the same behavior using existing API primitives, such as reference frames:
1. when a stacking context has an origin, we push another reference frame for it
2. when computing the sticky frame scroll port, we take this origin into account
This slightly simplifies Gecko-WR API, but more importantly it would allow WR to
get rid of this logic (of handling origins), which in turn would allow to switch
the reference frames from push()/pop() model to just define(), like we do for
scroll/sticky frames already.

Converted NS_STYLE_BORDER_STYLE_* consts to enum class. Updated corresponding values to enum class. reduced BCCornerInfo struct values to fit StyleBorderStyle values inside struct. Added defaults to switches that do not fully cover all instances of StyleBorderStyle.
Previously, the ASR overrides contained Maybe<ClipId>, where Nothing() corresponded to taking the top of the clip/scroll stack instead of overriding. This change removes the associated complexity by ensuring that we always provide the ClipId.

This change eliminates
- nsLayoutUtils::LastContinuationOrIBSplitSibling calls for each CSS
properties on WebRender
- iterating over each display item for each compositor runnable CSS properties
- a bunch of stuff in the case where the layer manager has not yet created,
i.e. the compositor thread is not ready to receive animations

In this case aAncestor is an SVGOuterSVGFrame, and aItem is a transform item for
its AnonChildFrame.
I'm not sure if it's quite expected to have such a frame generating a
transform...
Let me know if not and I can try to dig more, but this looks intentional given
the comment in nsSVGOuterSVGAnonChildFrame.

It doesn't make much sense to return const UniquePtr<Foo>& for something that
can't be null, it's just confusing.
Also make more stuff actually const.

This commit attempts to lower the pain of modifying FrameMetrics.h.
It looks like most includes really only want ViewID or
ScrollableLayerGuid, so this commit factors them out into a separate
header. In the process FrameMetrics::ViewID is changed to
ScrollableLayerGuid::ViewID, which personally seems like a better
place for it now that we have RepaintRequest. Unfortunately that
requires a lot of places to be updated.
After this commit there are still a couple of major places that
FrameMetrics is included.
* nsDisplayList.h
* nsIScrollableFrame.h
* Layers.h
Those are going to be more tricky or impossible to fix so they're
not in this commit.

The implementation of deferred transforms did not handle the case where
we ended up deferring multiple transform items before encountering the
APZ-relevant display item. In this case we need to somehow accumulate
all the deferred transforms. This patch accomplishes that, and includes
a mochitest that exercises the relevant behaviour.

First, we generate StyleComputedTimingFunction by cbindgen from Rust, and use
it in nsTimingFunction, so we could copy it directly without handling
the different memory layout. However, we have to rewrite the
nsTimingFunction and mozilla::ComputedTimingFunction for this.
Second, the rust-bindgen seems cannot generate the correct generic members
from complex C++ templates, especially for the nested template struct,
(https://github.com/rust-lang-nursery/rust-bindgen/issues/1429)
So we have to hide StyleTimingFunction to avoid the compilation errors.
