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?

Treat top-level number in calc() invalid
<!-- Please describe your changes on the following line: -->
This should probably considered as a temporary fix (for [bug 1321206](https://bugzilla.mozilla.org/show_bug.cgi?id=1321206)), to avoid assertion when trying to serialize calc value with only numbers. Certain properties (e.g. `line-height`) would eventually need to keep numbers inside calc.

Currently, CalcLengthOrPercentage doesn't actually keep the number value. If we don't treat it invalid, we can end up generating empty `calc()` value when one contains numbers (e.g. `calc(1)`), which would violate assertion elsewhere that `calc` must not be empty.

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.
This patch introduces infrastructure for the rule tree, and constructs it.
We don't use it yet, nor have good heuristics for GC'ing it, but this should not
happen anymore once we store the rule node reference in the node.
I haven't messed up with memory orders because I want to do a try run with it,
then mess with them.
Take down the ApplicableDeclarationsCache, use the rule tree for doing the cascade.
Use enum BorderWidth instead of a tuple-like struct to store the specified
value. BorderWidth is needed to be used in both longhand and shorthand
border width properties, so I put it in `specified` module.
Fixed#13869.
Fix radial gradient's <size>/<ending-shape> parsing
<!-- Please describe your changes on the following line: -->
Parsing now handles sizes and shapes in various order.
I had to delete `EndingShape`'s parse implementation and mix it with `Position` in `parse_radial`. It became a bit complicated to read but I couldn't make it simpler.

Expressions with percentages may be negative or positive at computed value time.
So, we can only clamp lengths at computed value time, which is what the other
browsers do.
Handle specialized serialization of <position> in basic shapes
Fixes#13083
We temporarily broke basic-shape serialization in #13042 when 4-value positions were implemented, since I didn't want to increase the scope of that PR too much.
This fixes it.
