Remove windows-gnu build code
<!-- Please describe your changes on the following line: -->
This is a follow-up to servo/saltfs#620.
There are three other places `windows-gnu` is mentioned, I'm not sure if they can also be removed or not:
- `nightly-x86_64-pc-windows-gnu` is listed as a target in the `appveyor.yml` build matrix
- 2 uses inside `host_platform` in `python/servo/util.py`
- The `windows_gnu` bootstrapper in `python/servo/bootstrap.py`

Add parsing/serialization for grid-{row,column} and grid-area
With this, almost all the grid properties will have been covered in Stylo. I now realize that we have only two more shorthands left to go - `grid` and `grid-template` (both require #16067)

Generate valid form for {background|mask}-position
<!-- Please describe your changes on the following line: -->
This issue is reported at https://bugzilla.mozilla.org/show_bug.cgi?id=1355017.
The following style
> background-position-x: 10%;
> background-position-y: top 3em;
generates
> background-position: 10% top 3em;
which is invalid. The correct form is
> background-position: left 10% top 3em;
The serialization of background-position should be implemented as a whole rather than just calling `to_css()` on its two longhand properties separately.
spec: https://drafts.csswg.org/css-backgrounds-4/#propdef-background-position

If there is any longhand consisting of both keyword and position, we
should attach both keyword and position for both longhands when serialize
them.
1. To generate a serialized result with keyword, we add a macro function
`to_css_with_keyword` accepted HorizontalPosition and VerticalPosition as
the parameter to finish that. For the longhands which missing keyword, we
use the default keyword.
(`left` for `*-position-x` and `top` for `*-position-y`)
2. Update `Position::to_css` to generate the valid format by calling
`to_css_with_keyword` with HorizontalPosition and VerticalPosition.
3. Update `to_css` to use new `Position::to_css` in background,
background-position, mask and mask-position.

Fix -moz-outline-radius shorthand serialization
<!-- Please describe your changes on the following line: -->
These changes aim to solve #15169 correcting the `ToCss` implementation for `LonghandsToSerialize` for the `border-radius` shorthands. They also reduce redundant values like `1px 2px 1px 2px` to `1px 2px` to either sides of the slash.

To simplify adding additional data to `ParserContext`, this moves test usages to
a few shared locations, instead of being spread across many tests.

Update WR (new border code path).
This includes the new border code path for simple (solid) borders.
This gives much higher quality border rendering, including proper
support for elliptical border segments.
The quality on https://github.com/servo/servo is noticeably improved.

Check for merge commits with tidy
<!-- Please describe your changes on the following line: -->
Tidy checks the last merge commit and their author and reports an error if the **last merge commit**'s author is not `bors-servo`.
In case the tidy test is run under Travis (checked by looking at the [value of the `TRAVIS` environment variable](https://docs.travis-ci.com/user/environment-variables/#Default-Environment-Variables), the number of commits looked at from `git log --merges` is two, and the second last merge commit is checked, since, from the [Travis docs](https://docs.travis-ci.com/user/pull-requests/#My-Pull-Request-isn%E2%80%99t-being-built):
> We rely on the merge commit that GitHub transparently creates between the changes in the source branch and the upstream branch the pull request is sent against.
So this is the test that I did:
```
$ git pull upstream master
...
$ git log --merges

Support line number offsets for inline stylesheets
<!-- Please describe your changes on the following line: -->
This allows accurate line numbers when reporting stylesheet errors.
@jdm This is going to require some effort to merge my changes with other recent changes to `ParserContext`. Because of that I would appreciate a quick sanity check before I put the time into performing the merge.
For example, should I store the `offset` as a u64, or should it be an Option?
