Make text decoration testable and do not serialize initial text-decoration-style
Servo now uses the same name for the text-decoration-line longhand property as Gecko. This was done to enable testing of the text-decoration shorthand.
The text-decoration shorthand has been fixed to not serialize initial text-decoration-style.

Shorthand cannot represent CSS-wide keyword in individual longhands, and
thus we cannot serialize longhand with CSS-wide keyword as part of a
shorthand.

Background serialization of multiple values.
Similar to animation, the serialization of multiple backgrounds should
return the longhands serialization if there are an unequal number of
values for the required properties. This is part of #15398

Similar to animations and backgrounds, multiple transitions should be
serialized as a list of shorthand values only if the number of values
for each longhand property is the same. Otherwise we default to the
longhand serialization. Fixes#15398

Fix animation serialization 15398 pt2
Fixes animation serialization so that an animation shorthand is serialized only when the value lists have the same length (part of #15398)
There are two commits here - the first is a refactoring to update PropertyDeclarationBlock::to_css to match the spec (please see the full commit message for perhaps too many details).
The second commit utilizes the changes in the first, and updates the animation serialization itself to write an empty serialization if the longhand value lists have different lengths, as per the original issue.
Interestingly, the refactoring of the first commit simplified quite a lot more than the fix for this bug, in particular, the special case of 'overflow' shorthand serialization is handled by default, without the extra special case code (now removed).

Fixes#15398
The previous commit did most of the work here of updating the algorithm
to skip shorthands if a shorthand value was an empty string. This commit
just updates animations LonghandToSerialize's implementation of
to_css_declared to write an empty string value if the list lengths
differ (and updates the test to match).
geckolib: use a global thread pool for styling
By having a single thread pool, rather than one per document, we use less memory. This addresses https://bugzilla.mozilla.org/show_bug.cgi?id=1324250.
This may be obvious to an experienced Rust programmer, but I went with raw pointers because trying to use `Option` global variables resulted in complaints about turning on feature flags in nightly Rust. Since this is for stylo, nightly features are not appropriate here.
