failing test for correct to_css of "width"
separate test for mq and to_css
implement css serialization for Eq
remove PASS test expectation
remove FIXME
simplify serialization
I realized that I fixed this issue incorrectly when the test failed before. Our design
document specifies that restyle hints must be expanded by the parent before traversing
children, so that we can properly apply LaterSiblings restyle hints. This includes
parents that do not themselves need processing (StylingMode::Traverse).
So we need to preprocess children even in the case where we don't restyle the parent.
On the flip side, we do in fact know whether a child needs processing before enqueuing
it, so we can skip the conservative visit I added before.

Implement parsing/serialization and/or gecko glue for some properties
<!-- Please describe your changes on the following line: -->
The PR covers implementation and/or gecko glue for these properties:
1. Implemented parsing/serialization and gecko glue for column-rule-width, column-rule-color and column-span longhand properties (column-span is not implemented in gecko yet but I wanted to complete column properties :) )
2. Implemented parsing/serialization and gecko glue for text-emphasis-color longhand and text-emphasis shorthand properties.
3. Implemented gecko glue for column-gap and order properties
I implemented column-rule-width and column-rule-color properties with `-moz-` prefixes, but I can remove them if it's not right.
I coudn't test them in full stylo build yet (LLVM messed up my current clang). But I'll test them soon.

Some generic impls for Either<Length, T>
<!-- Please describe your changes on the following line: -->
We seem to be using `parse_non_negative` a lot for `LengthOrFoo` types, so it's better to have generic impls (now, and in the future) for such things (assuming that `Length` will always be in the first variant of `Either`).

We only consider doing a GC currently if the root node has a zero refcount.
But that only happens if it has no children -- even weak children keep a
strong reference to their parent. So at the very least, we should do a
GC specifically when the RuleTree is going away. (We probably want to add
some other GC opportunities too at some point, otherwise it's easy to
never GC a RuleTree.)
