A single transition value that includes 'none' for transition-property is
valid, so we should store whole specified values (if it's valid). Whereas,
the spec [1] clearly says for the case where there are multiple entries;
If there is more than one <single-transition> in the shorthand, and any of
the transitions has none as the <single-transition-property>, then the
declaration is invalid.
'none 2s linear 2s' is a test case for the former, '1s width, 2s none' is a
test case for the latter.
Note that with this patch, 'transition: none' is serialized as 'none 0s ease 0s'
instead of 'none' but it matches Gecko.

Support None and NotSet for the fallback type of SVGPaint.
<!-- Please describe your changes on the following line: -->
We didn't set None and NotSet for the fallback type of SVGPaint, and it caused the fallback color is wrong when fallback color is empty or keyword `none`. So, we add the None and NotSet support for it.

Add support for position:sticky
This leverages the position:sticky support in WebRender to bring basic
support for position:sticky in Servo. There are still some issues with
nested sticky flows as well as a few other corner cases. Tests are
imported from WPT and can be removed once we update to the latest
version.

Reduce usage of fmt in serialization and error reporting
`format!` and `write!` create a somewhat-heavyweight `Formatting` struct and use dynamic dispatch to call into impls of `Dispaly` and related traits. The former also allocates an intermediate string that is sometimes unnecessary.
I started looking into this from https://bugzilla.mozilla.org/show_bug.cgi?id=1355599, but I expect the impact there will be small to insignificant. It might be a slightly less so on parsing (error reporting).

I want to play with autogenerating style structs, and color is the smallest
struct out there.
However, moving it out of the mako file is a requirement. This patch does that.
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.

There are already these tests in dom/smil/tests of gecko, this PR will enable these tests.

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.

style: Avoid scanning the longhand id twice in the fast path of PropertyDeclarationBlock::parse_common
This makes the overhead of this function much lower according to `perf`.
And in general makes sense, removing overhead from the fast path.

That literally made no sense, and is probably leftover from where we passed Map
directly there.
