Do not skip parent display-based style fixups for NAC that is not a NAC root
Stylo is currently skipping parent display-based style fixups for all NAC,
whereas we probably only want to do this for NAC roots.
In this patch, we ensure that we skip it for NAC roots, and pseudo-elements,
but not other NAC.

Skip adding/accumulating ClipRect values which corresponding rect offset is auto.
<!-- Please describe your changes on the following line: -->
This is a PR for https://bugzilla.mozilla.org/show_bug.cgi?id=1390352
This patch will skip adding/accumulating the values which corresponding rect offset is auto, and make Servo_AnimationValues_ComputeDistance return negative value instead of 0.0 when the function fails to distinguish its failure.

Update rust-webvr to 0.8
<!-- Please describe your changes on the following line: -->
The new rust-webvr version includes features like multiview, opaque framebuffers and multiple layer rendering support that will land in separate PRs.
It also splits rust-webvr traits to a separate crate. This allows much faster compilations when using local cargo replaces.

stylo: Bug 1390039 - Implement compute_distance for mismatched transform lists.
Implement ComputeSquaredDistance for mismatched transform lists.
In order to do this, we have to convert a transform list into a 3d matrix,
so I move the code from layout module into style module for reusing it.
