This commit adds the multi-position gradient color-stops syntax.
GradientItem::parse_comma_separated is extended to attempt to parse
a LengthOrPercent after each color stop. If it succeeds, it appends
an additional color stop with a duplicate color and the specified
position.
This change is only to the parsing, serialization is left unchanged
as per [1].

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.

Port `width`, and also add the `scan` media feature so I don't need to add
ugliness just to workaround the unused keyword_evaluator macro.
This is not part of the Gecko build in any case.
To support that, this patch also does the following.
- Removes the insert(), remove() and might_contain() methods, because they are
specialized versions of insert_hash(), remove_hash(), and
might_contain_hash(), and they are only used by tests within this file.
- Moves hash() from the top level into create_and_insert_some_stuff().
- Changes create_and_insert_some_stuff() so that instead of hashing consecutive
integers, it instead hashes stringified consecutive integers, which matches
real usage a little better.
- Raises the false_positives limit a little to account for the above changes.

We match with AllLinksVisitedAndUnvisited for style invalidation, and we already
do a subtree restyle because :visited matching doesn't depend on the actual
element state.
So all this stuff is just not needed. The comment points to the attribute tests
in bug 1328509, but those still trivially pass with this change.
I think this was unneeded since I introduced AllLinksVisitedAndUnvisited, or
maybe since https://github.com/servo/servo/pull/19520. In any case it doesn't
really matter, and I already had done this cleanup in my WIP patches for
bug 1406622, but I guess this is a slightly more suitable place to land them :)

Correctness improvements:
* UTF errors are handled safely per spec instead of dangerously truncating
strings.
* There are fewer converter implementations.
Performance improvements:
* The old code did exact buffer length math, which meant doing UTF math twice
on each input string (once for length calculation and another time for
conversion). Exact length math is more complicated when handling errors
properly, which the old code didn't do. The new code does UTF math on the
string content only once (when converting) but risks allocating more than
once. There are heuristics in place to lower the probability of
reallocation in cases where the double math avoidance isn't enough of a
saving to absorb an allocation and memcpy.
* Previously, in UTF-16 <-> UTF-8 conversions, an ASCII prefix was optimized
but a single non-ASCII code point pessimized the rest of the string. The
new code tries to get back on the fast ASCII path.
* UTF-16 to Latin1 conversion guarantees less about handling of out-of-range
input to eliminate an operation from the inner loop on x86/x86_64.
* When assigning to a pre-existing string, the new code tries to reuse the
old buffer instead of first releasing the old buffer and then allocating a
new one.
* When reallocating from the new code, the memcpy covers only the data that
is part of the logical length of the old string instead of memcpying the
whole capacity. (For old callers old excess memcpy behavior is preserved
due to bogus callers. See bug 1472113.)
* UTF-8 strings in XPConnect that are in the Latin1 range are passed to
SpiderMonkey as Latin1.
New features:
* Conversion between UTF-8 and Latin1 is added in order to enable faster
future interop between Rust code (or otherwise UTF-8-using code) and text
node and SpiderMonkey code that uses Latin1.

It used to be this way because of lifetime issues (plus the shadow

We only have this so that ::-moz-placeholder keeps serializing as
::-moz-placeholder, but I don't think anybody really cares.
Edge aliases ::-webkit-input-placeholder to ::-ms-input-placeholder at parse
time as well, as can be seen in:
```
let s = document.createElement('style');
s.innerHTML = `input::-webkit-input-placeholder { color: red };`;
document.body.appendChild(s);
document.body.innerHTML = s.sheet.cssRules[0].cssText;
```
And I think this is more consistent with what we do for CSS properties that are
aliases.

Always assume allowed-for-all-content. There are a couple callers which weren't
doing that:
* A unit test -> removed.
* ComputeAnimationDistance: Used for testing (in transitions_per_property), and
for the animation inspector. The animation inspector shouldn't show
non-enabled properties. The transitions_per_property test already relies on
getComputedStyle stuff which only uses eForAllContent.
* GetCSSImageURLs: I added this API for the context menu page and such. It
doesn't rely on non-enabled-everywhere properties, it was only using
eInChrome because it was a ChromeOnly API, but it doesn't really need this.

The values in the boolean context depend on its feature. For examples, in the
case of prefers-reduced-motion 'no-preference' means false and 'reduced' mean
true in the boolean context, whereas in the case of prefers-contrast
'no-preference' means false and other two values, 'high' and 'low' means true
in the boolean context. To support it we introduce a child struct of
nsCSSKTableEntry that has an additional field representing the value in the
boolean context and use it when we have no specified value in the media feature
(i.e. in the boolean context).

Summary:
This fixes a couple fuzz bugs and prevents special-casing <svg:use> even more in
bug 1431255.
Unfortunately not as many hacks went away as I'd have hoped, since we still need
to match document rules, see the linked SVGWG issues.
But blocks_ancestor_combinators goes away, which is nice since it's on a very
hot path.
Test Plan: WPT for style invalidation, covered by existing tests otherwise.

If we have a rotate axis whose length is extremely large, we will get an
infinite value, and its normalized vector is a zero vector, instead of an
unit vector, i.e. (x/inf, y/inf, z/inf) == (0, 0, 0).
The solution is: we scale the vector, so the length becomes a finite value,
and we could get a valid unit vector. Therefore, we use
a different normalization method, robust_normalize().

The EffectSet count does not exactly represent the count what we really need
for AnimationValueMap, but in most cases it matches. For example;
1) The element has two different keyframes animations
@keyframes anim1 {
to { opacity: 0; }
}
@keyframes anim2 {
to { transform: rotate(360deg); }
}
In this case the number matches.
2) The element has two animations but both keyframes have the same CSS property
@keyframes anim1 {
to { opacity: 0; }
}
@keyframes anim2 {
to { opacity: 0.1; }
}
In this case the number doesn't match, moreover it results more memory than we
ever needed, but this case is presumably less common.
3) The element has an animation having keyframes for two different CSS
properties.
@keyframes anim {
from { opacity: 0; transform: rotate(360deg); }
}
In this kind of cases, the number doesn't match. But even so, this patch
reduces the opportunities that the AnimationValueMap tries to allocate a new
memory (i.e. less opportunities on expanding the map).
Note that when the hash map is expanded, we do allocate a new RawTable with the
new size then replace the old one with the new one [1], so I believe this
change will reduce the crash rate to some extent.
