In the next patch, we'll move logic to identify the children for traversal into
preprocess_children (which will be renamed), and the set_dirty_descendants logic
will move along with it. So left as-is, the code here will clobber the flags.

This allows us to have ensure_data() and clear_data() functions on the TElement
trait, instead of hacking around it adding methods in random traits.
This also allows us to do some further cleanup, which I'd rather do in a
followup.
Sync Servo / Gecko image-orientation rounding; pass as enum.
Make Servo's rounding of image-orientation values agree with Gecko's,
and pass orientations directly as an enum instead of as angles.
Depends on a Gecko change to be subsequently landed in m-c.

It was storing both TrackSize and TrackRepeat before and TrackRepeat have to be
converted into sequence of TrackSize during serialization. Instead of doing this
in serialization process(which is hard and hacky), we converted to do this in
parsing process. We were doing this conversion in the ComputedValue conversion.
So we only had to move this process to parsing.

Remove WindowNavigateMsg
Two reasons:
- We want to be able to jump further in history from the embedder.
- We don't want to have an extra translation step in the compositor, where `WindowNavigateMsg` is translated to `TraversalDirection`

Improve font layout in Linux / Freetype platforms.
This patch contains two small changes:
* Fix the font size calculation that is passed to Freetype. This
now matches exactly how Webrender and Gecko calculate font size
to pass to layout.
* Enable light hinting by default for fonts when using Freetype.
We should make this configurable in the future, but this is a
better default than no hinting (and matches what most Linux
distros default to).
These two changes (along with the pending WR update) fix a lot
of the font layout issues on Linux. There is still at least one
remaining issue with hidpi displays on Linux that will be fixed
in a follow up patch.

style: Don't stop looking at the sharing cache for various reasons.
All the information that made those failures expensive is now lazily computed
and cached, or eagerly computed anyway, so seems not worth to stop iteration.

Have CharacterData call children_changed on its parent when data is set.
**Can't run WPT on my computer, so pushing here to run tests 😢**
Have CharacterData.SetData call children_changed on its parent when
data is set (if it is a Text node) so that HTMLStyleElement parents can
re-parse. Add variant ChildrenMutation::Text for it to use as the
mutation.
This fixes an issue where an empty <style> element's data is set but the
style is not updated. An HTMLStyleElement parent re-parses in its
children_changed implementation.

Fix the size and position of overflow:scroll clip
The clip for overflow:scroll clip was not including the space for
padding, which could lead to some content being clipped when it
shouldn't. This changes fixes that issue.
A test is skipped because this fix also stops hiding a failure due to
mispositioned text.
Fixes#16576.

Reduce amount of Mako-generated code in style
In multiple places, instead of generated similar code for each CSS property, have a single code path that uses an enum such as `LonghandId`.
Fix https://bugzilla.mozilla.org/show_bug.cgi?id=1377262
Machine code size is measured with [bloaty](https://github.com/google/bloaty), looking at the total "VM size" in order to exclude debug info (which is stripped in binaries shipped to users).
```
mach build-geckolib --release
bloaty target/geckolib/release/libgeckoservo.a
```
Initial size was 9.56Mi. Successive commits in this PR bring it to 9.55Mi, 9.51Mi, 9.44Mi, 9.31Mi, 8.89Mi, 8.89Mi, and 7.54Mi. Total savings: 2.02 MiB.
In an optimized Firefox build with `mach build && mach package`, the size of `obj-x86_64-pc-linux-gnu/dist/firefox/libxul.so` goes from 109.11 MiB to 107.49 MiB, saving 1.62 MiB. I don’t really know how to explain the difference. Does `libgeckoservo.a` contain code that ends up not being used in `libxul.so`?
