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 matches the spec, https://drafts.csswg.org/css-values/#angles, which says:
> All <angle> units are compatible, and deg is their canonical unit.
And https://drafts.csswg.org/css-values/#compat, which says:
>When serializing computed values [...], compatible units [...] are converted into a single canonical unit.
And also other implementations (Blink always serializes angles as degrees in
computed style for example).
Also allows us to get rid of quite a bit of code, and makes computed angle value
representation just a number, which is nice.

I had to fix the conversion for BackgroundSize too, hopefully we can
simplify all this using cbindgen in the future instead of CalcValue.

For now, |clip-path: path()| is chrome-only, and not for shape-outside,
so we only implement the parser for clip-path. Besides, I didn't put
path() in BasicShape because path() doesn't use the reference box to
resolve the percentage or keywords (i.e. SVG path only accept floating
point or integer number as the css pixel value). Therefore, I add it into
ShapeSource, instead of BasicShape.

SVGPathData will be used by clip-path and offset-path (and/or more on the
properties which support <basic-shape>). Therefore, let's move
SVGPathData out of motion.rs.

The implementation of ToCSS for Polygon has some rule, and we could use skip_if
to handle and serialization of fill-rule. However, we should derive ToCSS for
the pair of LengthOrPercentages, so define a new type for it.

Define OffsetPath & SVGPathData on the servo-side, and StyleMotion &
StyleSVGPath on the gecko-side. We parse the SVG Path string into a
vector of PathCommand. To build the gfx::Path, we will convert it into
gfx::Path later in a different patch.
The basic flow is:
- Parse SVG Path String into SVGPathData (in Rust).
- Use cbindgen to make sure the layout of PathCommand and StylePathCommand, and then set the Box[PathCommand] into nsTArray<StylePathCommand>.
- Try to convert nsTArray<StylePathCommand> into gfx::Path. (This part will be implemented in a different patch.)
Finally, we use the gfx::Path to create a motion path transform.
The layout implementation is in the later patch.
Depends on D2962

1. We will add more shape-like types in the future, so it's better to
use union to reduce the memory usage.
2. Those shape-like types are mutual exclusive, so we could use union to
wrap them.

There were a check in CssUrl::parse_from_string for extra data, which
was removed as part of servo/servo#16241, so it never fails now.
CssUrl::from_url_value_data doesn't seem to need Result from the very
beginning. It is unclear why it was made that way.

This should fix the following two "expected to fail" tests:
- getComputedStyle(elem) for url() listStyleImage uses the resolved URL
and elem.style uses the original URL
- getComputedStyle(elem) for url() listStyle uses the resolved URL
and elem.style uses the original URL
In stylo, ComputedUrl and SpecifiedUrl happen to be the same. However, using
ComputedUrl can make code clearer that conversion.rs is for converting
computed values between gecko and servo types.
We replace Au with CSSPixelLength for the length part of
computed::CalcLengthOrPercentage. Therefore, it would be easier to use
CSSPixelLength for all other LengthOrPercentage{*} types.
First, we define computed::CSSPixelLength which contains a CSSFloat, a
pixel value, and then we replace computed::Length with CSSPixelLength.
Therefore, the |ComputedValue| of NoCalcLength, AbsoluteLength,
FontRelativeLength, ViewportPercentageLength, CharacterWidth, and
PhysicalLength is CSSPixelLength.
Besides, we drop NonNegativeAu, and replace computed::NonNegativeLength
with NonNegative<computed::Length>. (i.e. NonNegative<CSSPixelLength>)
