9517190a60 Split stacking context fragments into sections in layout_2020 
This allows rendering stacking context content in the proper order. We
also need to add a new pseudo stacking context for atomic inlines in
order to preserve proper rendering order in some cases.

4a2787b974 Add initial stacking context paint order support to layout_2020 
This adds very rudimentary support for paint order in stacking context.
In particular z-index is now handled properly, apart from issues with
hoisted fragments.

843df5b529 Add support for a stacking context pass to layout_2020 
This adds an intermediary data structure that allows the display list
builder to move through the fragment tree in stacking context painting
order. Spatial nodes are built during this phase and all display list
items are added to the end of the display list.

layout_2020: Avoid decomposing mixed length / percentages in intrinsic sizing. 
As that makes no sense in presence of min / max.

layout: Resolve word_spacing ahead of time. 
It's not possible anymore, in the presence of min() / max(), to split a
<length-percentage> value into a <length> and a <percentage> component.

Tweak word_spacing to do what Gecko does (resolving it in advance).

63aae0178f Improve position:fixed support in layout_2020 
This makes it so that position:fixed elements do not scroll with the
rest of the contents, but does not tackle the rest of the issues with
their positioning.

This makes things a big easier to read and will make it easier to add
support for position:fixed.

7a5a320d74 Add support for overflow:scroll and overflow:hidden to layout_2020 
This adds clipping and interactive scrolling support, but scrolling from
script is still not functional.

02deb99a05 Use euclid data types for physical structs in layout_2020 
This removes a bit of duplication and allows layout_2020 to benefit from
a much richer set of utilities.

1cd772fe5f Answer content box queries for layout_2020 for the root element 
This isn't correct yet, but it is necessary to give a value in order for
scrolling from script to work. Later this should give an accurate
content box response as well as work for non-root elements.

27e0400891 Fix an issue with unset_boxes_in_subtree in layout_2020 
If the root node of the subtree doesn't have any boxes to unset, we
should exit early instead of unsetting boxes on siblings of the root.
This eliminates an infinite loop in this method, since the siblings of
the root are not in the subtree.

8825d588c1 Add initial support for scrollable overflow in layout_2020 
This still isn't totally correct and non-root scrolling is not handled
at all, but the root frame now scrolls.

Auto merge of #25512 - servo:background-image, r=nox 
Render `background-image: url(…)`

… and support most `background-*` properties.

Still to do:

* `background-attachment`
* Gradients
