* `LonghandId` and `ShorthandId` are C-like enums
* `Atom` is used for the name of custom properties.
* `PropertyDeclarationId` is the identifier for `PropertyDeclaration`,
after parsing and shorthand expansion. (Longhand or custom property.)
* `PropertyId` represents any CSS property, e.g. in CSSOM.
(Longhand, shorthand, or custom.)
Using these instead of strings avoids some memory allocations and copies.
This allows us to control whether the catchall case in the match expression
that maps Gecko const to Servo enum will be generated.

Remove usage of 'keyword_list'
<!-- Please describe your changes on the following line: -->
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.

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)
