Clearance was implemented as a Length, where zero meant no clearance.
However, having a clearance of 0px should be different than having
no clearance, since the former can still prevent margin collapse.
This patch keeps the existing behavior, so it won't be possible to get
a clearance of Some(Length::zero()), but it prepares the terrain for
a follow-up to fix calculate_clearance to return the proper thing.
Properly position floats when subsequent boxes collapse margins with containing block
Margins should be able to collapse through floats when collapsing with
parent blocks (the containing block). To properly place floats in this
situation, we need to look at these subsequent floats to find out how
much of the margin will collapse with the parent.
This initial implementation is very basic and the second step would be
to cache this in order to avoid having to constantly recalculate it.
Fixes#29915.

Remove the DOMToTexture feature
This relies on WebRender's frame output API, `set_output_image_handler`,
which has been removed from the latest upstream [1]. It's sad to remove
this feature, which was probably a lot of work to implement, but it
seems difficult to patch WebRender to restore this functionality.
Fixes#29936.

Refactor ServoParser Tokenizer to return TokenizerResult
As stated in #25516, this PR refactors the feed functions in the following files to return an Option instead of a Result:
- components/script/dom/servoparser/async_html.rs
- components/script/dom/servoparser/html.rs
- components/script/dom/servoparser/xml.rs
- components/script/dom/servoparser/mod.rs
Originally, these functions were returning the Err values for situations that didn't actually result in an error. This PR fixes that.

Properly position absolutes with static insets that are children of floats
Previously, final float positions were calculated when their parents
were positioned. This prevented proper positioning of absolute children
of floats with static insets, because they accumulate offsets as they
are hoisted up the tree.
This change moves the final float positioning to
`PlacementState::place_fragment` for the float itself so that it happens
before any insets are updated for hoisted descendants. In addition to
simplifying the code, this makes it a bit more efficient. Finally,
floats are taken into account when updating static insets of hoisted
boxes.
Fixes#29826.

Fix interaction of clearance with margin collapse
In #29897 I did the simple naive thing, but it wasn't entirely correct. This patch tries to address the problems. In particular:
- Clearance should prevent margins from collapsing through if it happens between them, as opposed to on the element that owns them.
- The margins of an element with clearance can still collapse through, and collapse with other siblings as normal, but the resulting margin can't collapse with the bottom margin of the parent.
