Generates `SupportedPropertyNames` on DOM structs that should implement
it. Most of them are unimplemented now (which can be implemented in
later PRs), with the exception of `HTMLCollection`. Also added a couple
relevant WPT tests.

layout: Use the value of the `max-width` property when speculating what the inline sizes of block formatting contexts are likely to be.
Usually, Web developers set this property on block formatting contexts
in order to avoid running into floats, and we can use this as a
speculation hint.
Fixes the width of the search box on the Google SERPs.

Avoid a panic when handling collapsing borders (fixes#7144)
There is no need to compute next_collapsed_borders_in_block_direction for all kind of flows when it's used only in the table row case. That also avoids a panic when the next child is a table colgroup (this should not happen when iterating over a table row).

layout: Improve our handling of inline absolute containing blocks.
Several issues are addressed in this commit:
* Inline flows now bubble up their absolute descendants instead of
making the inline flow the containing block for them. (In the future,
we will need to make the inline flow *sometimes* be the containing
block for them, but for now it improves sites to unconditionally
bubble up.)
* Fragments now look at their inline fragment context to determine
whether they are positioned.
* Inline flows now push the stacking-relative position of the absolute
containing block down to their inline-block fragments.
* Inline absolute hypothetical fragments can be containing blocks.
* Fixes the logic in
`containing_block_range_for_flow_surrounding_fragment_at_index`. The
condition to determine whether fragments are positioned was inverted!
* `Descendants`/`AbsDescendants` has been refactored in order to become
more friendly to inline absolute containing blocks in the future.
Improves the inline position of the green drop-down arrow in the Google
SERPs. (The block position is still wrong.)

into account only once.
There were two bugs here: (1) relative position applied to
scanned/unscanned text fragments independently of the container element
that applied that relative position, causing double-counting; (2)
relative position applied to inline block fragments independently of the
wrapped block itself, causing double-counting.
This commit also removes the `cascade_anonymous` function and the
related `Fragment` constructor. They were unused, and their
functionality has been replaced by the `modify_style_for_*` series of
functions.
Closes#7067.
