8de55695e4 Have transforms and filters be CBs for all descendants in layout_2020 
This is a feature that was never properly implemented in the previous
layout system. We still need to preserve their in-tree order in the
display list though.

c20c468814 Rename AbsolutelyPositionedBox::layout to AbsolutelyPositionedBox::to_hoisted 
This method doesn't actually do any layout, but converts this block to a
HoistedAbsolutelyPositionedBox which is hoisted and then laid-out with
its containing block later. This makes the code a little easier to read.

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.

f03026b869
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).

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.

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.

c44ee516a1 Give PositioningContext more responsibilities 
Iits details are now private to the module.

It has a couple methods that take closures to make sure that "before" and "after" steps are done together:

* In an absolutely positioned box, take care of nested abspos (establish a new containing block, etc.)
* For a box that *might* be `position: relative`, optionally take care of the same.
