Currently, Servo uses ComputeSquaredDistance derive for
SvgLengthOrPercentageOrNumber, so servo can't calculate between
LengthOrPercentage and Number.
This PR will allow calculating these value.
We need to use enum instead of Either since we can't interpolate stroke-* between
unitless length and unit length(e.g. '5' -> '10px').
This coomit make following:
* Introduce SVGLengthOrPercentageOrNumber on computed and specified values.
* Make SVGLengthOrPercentageOrNumber animatable.
* Make stroke-dasharray not-accumulate.
Make list-style-type animatable

More grid serialization and parsing fixes
These are the bugs I discovered while I was re-enabling the disabled grid mochitests. Now all grid mochitests are passing! Additionally I converted `Vec<CustomIdent>`'s into `Box<[CustomIdent]>`. We are storing so many line names in vectors. These should help a bit.

We have checks for these in the shorthand parsing side actually.
But if we need to serialize a group of longhand sub-properties for the shorthand,
we should be able to fail for invalid grammar gracefully. This patch adds these checks.
It was storing both TrackSize and TrackRepeat before and TrackRepeat have to be
converted into sequence of TrackSize during serialization. Instead of doing this
in serialization process(which is hard and hacky), we converted to do this in
parsing process. We were doing this conversion in the ComputedValue conversion.
So we only had to move this process to parsing.

Add support for subgrids and fix some other grid properties
This covers the `subgrid <line-name-lists>?` for `grid-template` (for gecko, and hence, stylo).

It was printing `repeat(n, <line-names>)` for number TrackRepeat.
But it should just print n times <line-names> instead.
