Remove usage of 'keyword_list'

We're using `keyword_list` to generate code for some of the animation properties. This could be achieved with `single_keyword` (passing `vector=True`).

Delegate logical bitfield setters to physical to fix cascade
(fixes#14222)
Five minutes early for "tomorrow", _shrug_.
I'm not entirely sure of this fix. It depends on properties going through the cascade in source order all else being the same. I think that's the case.
Fixes wikipedia though.

Immutable CSSOM
This PR is intended to add basic support for all CSSOM interfaces, with the ability to index `document.styleSheets` and css rule lists, and serializing individual css rules. Handling individual interface methods for CSSRule subclasses can probably be done with easy/medium bugs.
Mutation safety isn't dealt with here; if the css rule list is mutated the CSSOM will be in an inconsistent state. I intend to deal with this via zero sized tokens, see https://groups.google.com/forum/#!topic/mozilla.dev.servo/AnxJoVmtMXQ . I'll handle that when I start making the CSSOM mutable. (Getting the immutable bit landed first opens this up for easy bugs)
This doesn't really change style aside from adding an extra arc in the CSS rule list as discussed in the linked thread. So far this same design can be used by stylo as well when the time comes.

This commit itself only moves things around and adds an extra parameter to the
`apply_declarations` function to eventually handle #14079 correctly.
Probably needs a more granular API to query fonts, á la nsFontMetrics, but
that's trivial to do once this is landed.
Then we should make the font provider mandatory, and implement the missing stylo
bits.

Separate selector matching from property cascading

Support logical properties in style
Adds support for the logical block-end/inline-start/etc properties. These properties (like `border-block-end-color`) map to "physical" properties (e.g. `border-top-color`) depending on the writing mode.
Todo:
- [x] Handle shorthands
- [x] Make geckolib setters work
- [x] Handle padding/offset logical properties
- [x] Perhaps handle `-block-size`, `-inline-size` type logical properties?
- [x] Tests?
This will overall add 16 new longhands and 4 new shorthands, taking a big bite out of the [remaining properties work](https://manishearth.github.io/css-properties-list/?stylo=hide&servo=hide&firefox=only&chrome=show&mdn=false&alexa=false)

We can't assume all our siblings are alive because they may very well be in the
free list too.
This tempts to happen when the rule nodes are destroyed as part of the last GC,
the one that runs in the root destructor.
Also, properly put the next sibling back into the list when the rules are GCd.
