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
The match_ignore_ascii_case! macro does ASCII-case-insensitive matching.
In cssparser verion 0.11, it will require its patterns to be already
lower case.
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.
style: Adjust float if the element is positioned per CSS 2.1 section 9.7
We've found crashes related to this in Gecko.

Add support for keyword values for min-width and max-width
This is a follow-up to #14432 which got closed and can no longer be re-opened.
This PR aims to add support for keyword-values max-content, min-content, fit-content, and fill-available to the properties that use them, namely min-width, min-height, max-width, and max-height.
It's still untested because I still haven't figured out how to do that. I guess I should write or find some web page that uses these properties.

Implement gecko glue for clip property
<!-- Please describe your changes on the following line: -->
Implemented gecko glue for clip property.
Clip property looks slightly different in gecko. `auto` top and left values are preserved as auto in [gecko](http://searchfox.org/mozilla-central/rev/39e4b25a076c59d2e7820297d62319f167871449/layout/style/nsRuleNode.cpp#10294,10316) but converted to 0 in [servo](https://dxr.mozilla.org/servo/rev/65624dbfc28442b58145215f524eb13aeb2cadf6/components/style/values/specified/mod.rs#942). Gecko is setting `NS_STYLE_CLIP_TOP_AUTO` and `NS_STYLE_CLIP_LEFT_AUTO` flags with that information. But I tried this property in stylo build and it is working correctly like this. It looks like it doesn't change the outcome of the property.
~Do we really need to set these flags?~
Manishearth and bz said that auto and 0 values are same.

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).
Add support for most of the border-image properties, pass to WR.
This adds support for:
* border-image (images, not gradients yet)
* border-image-source
* border-image-slice
* border-image-repeat (stretch + repeat only for now)
Remaining work:
* Connect border-image-outset (WR supports this).
* border-image-width

Implement an ExtremumLength type which contains all the enumerated
keyword values for min-width, min-height, max-width, and
max-height. Then, implement a MinLength which can be used for min-width
and min-height. So far this just maps to Gecko values.
