This allows us to get rid of a bunch of lifetimes and simplify a lot of code. It
also lets us get rid of that nasty lifetime transmute, which is awesome.
The situation with thread-local contexts is still suboptimal, but we fix that in
subsequent patches.
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?

Fix the behavior of block-direction margins of replaced element both
as block level or inline level, and no longer query fragment info when
building display list for canvas.
Use `calculate_replaced_sizes()` in `compute_intrinsic_inline_sizes()`
and `assign_replaced_inline_size_if_necessary()`, and remove size
calculation in `assign_replaced_block_size_if_necessary()`, since
we've already done that.
These new methods calculate both the used width and height of an
replaced element and the same time. The `has_intrinsic_ratio()` method
also exposes information about whether a fragment has intrinsic aspect
ratio.

* `LonghandId` and `ShorthandId` are C-like enums

(Longhand, shorthand, or custom.)

The primary idea of this patch is to ditch the rigid enum of Previous/Current
styles, and replace it with a series of indicators for the various types of
work that needs to be performed (expanding snapshots, rematching, recascading,
and damage processing). This loses us a little bit of sanity checking (since
the up-to-date-ness of our style is no longer baked into the type system), but
gives us a lot more flexibility that we'll need going forward (especially when
we separate matching from cascading). We also eliminate get_styling_mode in
favor of a method on the traversal.
This patch does a few other things as ridealongs:
* Temporarily eliminates the handling for transfering ownership of styles to the
frame. We'll need this again at some point, but for now it's causing too much
complexity for a half-implemented feature.
* Ditches TRestyleDamage, which is no longer necessary post-crate-merge, and is
a constant source of compilation failures from either needing to be imported
or being unnecessarily imported (which varies between gecko and servo).
* Expands Snapshots for the traversal root, which was missing before.
* Fixes up the skip_root stuff to avoid visiting the skipped root.
* Unifies parallel traversal and avoids spawning for a single work item.
* Adds an explicit pre_traverse step do any pre-processing and determine whether
we need to traverse at all.

This avoids storing it in the rowgroup (which doesn't need it) and
ensures that it is done sequentially, which will be important when
rowspan support is added to this function.
Note that this does not reduce parallelism in the common case where
all rows are in the same rowgroup.
We want them to be children of the parent scrolling root instead of the
scrolling root of the particular block they belong to. Also, we adjust
the scroll root to only include the content region.

I realized that I fixed this issue incorrectly when the test failed before. Our design
document specifies that restyle hints must be expanded by the parent before traversing
children, so that we can properly apply LaterSiblings restyle hints. This includes
parents that do not themselves need processing (StylingMode::Traverse).
So we need to preprocess children even in the case where we don't restyle the parent.
On the flip side, we do in fact know whether a child needs processing before enqueuing
it, so we can skip the conservative visit I added before.
