This is the first step to unprefix user-select.
This has no behavior change, it's just a nicer way to do the same thing which
allows us to unship individual values more easily using parse(condition).

Basically, we rewrite the type of generics::transform::Translate and its
ToCss to match the spec. Besides, we always serialize Translate by servo,
so we could drop a lot of duplicated code.

Keep our old 'progressbar' as an alias for now, but unship
'progresschunk' by restricting it to UA/chrome sheets only.
Unship 'progresschunk-vertical' by removing it since it's
not used internally for anything.

The current spec says: "If only the X value is given, the Y value
defaults to the same value.", so we should update the behavior.
Besides, we also update the serialization, so we serialization both
specified and computed value by servo. We enable the preference
for all the css-transforms, so some of them are passed now.

With this change, all of Chrome, Edge, Firefox, and Safari serialize
background-size by omitting the second "auto" if the value is "auto
auto". Other keywords are still repeated.

Also remove specified-value-only keywords, since those are handled
only in Rust code and C++ doesn't need to know about them.

1. Add a new preference, layout.css.step-position-jump.enabled, for
step(_, jump-*) timing functions.
2. We still keep JumpEnd and End tags, even though there is no difference
between them. Therefore, we could disable the preference if needed.
3. Update the calculation of StepTiming to match the algorithm in the spec.
4. For servo, we implement the correct step function algorithm except
for the handling of before_flag. This could be fixed later.

First, we generate StyleComputedTimingFunction by cbindgen from Rust, and use
it in nsTimingFunction, so we could copy it directly without handling
the different memory layout. However, we have to rewrite the
nsTimingFunction and mozilla::ComputedTimingFunction for this.
Second, the rust-bindgen seems cannot generate the correct generic members
from complex C++ templates, especially for the nested template struct,
(https://github.com/rust-lang-nursery/rust-bindgen/issues/1429)
So we have to hide StyleTimingFunction to avoid the compilation errors.

We make sure the step number is always positive, so using
computed::Integer is safe and can derive ToComputedValue.

TimingFunction is defined in a separate spec (i.e. css-easing), instead
of transform, so we move it into a different file.

frames() timing function was removed from the spec, so we drop it.
Besides, some devtool tests are removed because they use frame(). I will
add them back by using new step function later.

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.

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].

There are a few mentions of nsRuleNode left but they are mostly
historical references so it makes sense to keep them.

We define the standalone types for using derive macro easily and overriding
the behaviors of this traits. This could avoid defining the general
behavior of booleans.

Here, we change the animation type of offset-path as ComputedValue, so
we could do animation on it. Also enable the wpt for offset-path
interpolation. In test_transition_per_property.html, we add some basic tests
ifor offset-path.
ToAnimatedZero for PathCommand will be dropped later.
Because the animations of arcs with mismatched flags are fallen back to
discrete animations, the result of getComputedValue is not normalized in this
case. This makes some wpt failed even though the progress is 100%.
