Implement background-position-x/y
<!-- Please describe your changes on the following line: -->
This is a WIP PR. Just HorizontalPosition / VerticalPosition implementations are complete. I would like to get early feedbacks about this architecture. Here's some architectural topics to consider:
- I created `HorizontalPosition` and `VerticalPosition` structs for this and used them in `Position` as well. We have decided to split `Keyword` enum, but we need them as unified for `PositionComponent` enum. So I didn't split but I can split it if we prefer to change PositionComponent as well.
- If we prefer Keyword enum like this, we can create a SubPosition(or something like this) instead of HorizontalPosition/VerticalPosition enums since only difference is 2 lines in `parse` functions. We can create a `parse_horizontal` and `parse_vertical` instead and a lot of code duplication can be cleared.
- I couldn't find a good way to use HorizontalPosition/VerticalPosition's parse functions in `Position`'s parse function. It is a bit more complicated. I'm open to suggestions :)
- I don't know much about logical keywords so do I need to do something different? I placed some comments where logical keywords are processing.
Any advice about these?

Added image-orientation property
<!-- Please describe your changes on the following line: -->
Implemented as per the MDN documentation—I could not find a current CSS draft. I am not sure if this is the complete correct metadata for the longhand helper:
```
<%helpers:longhand name="image-orientation”
experimental=“True”
animatable=“False”>
```
Also I am not sure how to test this and would appreciate help in creating a testing strategy.

* `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.

transition is the same as the end value for a running transition per
CSS-TRANSITIONS § 3.
Besides being contrary to spec, the old behavior could cause a cascade
of CSS transitions incorrectly triggering themselves when calls to
`getComputedStyle()` were intermingled with them.
Improves performance of nytimes.com.
