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.

Return Err(()) if determinant is not 1 or -1 while decomposing the 2d matrix
This error may happen in some cases, and we shouldn't panic in debug mode,
so let's return Err(()) for it to fall back to discrete animation.

Harden assert for creating atom from raw pointer
One of Stylo's common assertion turns out to be from having a null Atom (see [Gecko 1385925 bug comment 7](https://bugzilla.mozilla.org/show_bug.cgi?id=1385925#c7)). It would be helpful if we can catch this kind of crash earlier via a release-assertion.
This may regress performance to some extent which I'm not sure. But we can probably have it there for diagnosis for now, and remove later.

layout: Stop call normal block size assignment for flex container
No need to call the `assign_block_size_block_base()` method of normal block in flex.rs since it is implemented for CSS2.

enable antialiasing by default
This is not a problem for regular Servo because these values are toggled when the command line is parsed. But it's not the case when embedding Servo.

style: Avoid scanning the longhand id twice in the fast path of PropertyDeclarationBlock::parse_common

Use cssparser's new_with_line_number_offset
cssparser provides a way to set the initial line number on a
ParserInput. This patch changes servo to use this facility, rather than
reimplement the same functionality itself.
