* mach: use `importlib` module instead of `imp`
`imp` module has been deprecated since python 3.4
and has been removed in 3.12. The recommended alternative
is to use the `importlib` module that was introduced in
python 3.1
This is required to fix the CI failures in macos builds
since GitHub runner images for macos-13 now use python 3.12

Flattening the LineItem tree into a token stream will allow for handling
the case where an unbreakable line segment spans multiple inline boxes
which might have different hierarchies. This change also fixes the
handling of the second anonymous fragment of a block-in-inline-split.

This change adds and alternate method for triggering try changes.
Instead of comments, changes are triggered via applying labels to pull
requests. The action will remove the label from the request and start
the requested jobs.
This will require creating at least a few labels:
- T-full
- T-linux-wpt-2013
- T-linux-wpt-2020
- T-macos
- T-windows
More labels can be added as we support more configurations.
The good thing about this change is that try jobs against the actual
branch in the pull request instead of the master branch. This means
that changes to CI can be tested (unlike for comment processing).
One bit caveat with this change is that when adding multiple labels, a
CI job is triggered for each. Only one real build will run for each
label, but whether or more try jobs is triggered is a race condition.
The first CI job to successfully remove the label will actually trigger
the job. If the same job removes two compatible labels, then they can
share a build (for instance two types of WPT linux jobs). If not there
will be two. Note that this is at least as efficient as the current
behavior.
They are not transitionable:
https://drafts.csswg.org/css-transitions-1/#transitionable
There are some new failures in background-image-interpolation.html,
but I think the test is wrong, because it expects background-image
to be transitionable, even though the spec defines it with a discrete
animation type.
After placing a float, FloatBox's layout_into_line_items() was calling
place_line_among_floats() with ifc.current_line.inline_position as the
width of needed by the contents of the line.
The problem is that this amount includes the trailing whitespace advance
and thus it could seem that the in-flow contents wouldn't fit next to
the float.
That's not the case, since collapsible whitespace at the end of the line
is removed, and preserved whitespace hangs.
So this patch subtracts ifc.current_line.trailing_whitespace_advance
when calling place_line_among_floats(), like it was already happening
when computing the available_inline_size.
Fixes#30561
In legacy layout, anonymous text wrappers were inheriting the `overflow`
and `text-overflow` properties. This results in the creation of extra
clipping for these anonymous wrappers which could clip away floats. We
will likely implement `text-overflow` differently in non-legacy layout.
This change marks all legacy layout pseudo elements as "legacy" and also
adds a new pseudo element for non-legacy layout that does not inherit
`overflow`.
Fixes#30562.

Improve the calculation of the block size of line boxes and all their
component elements. Even empty spans can increase the size of the line
based on their font-size. Elements that have a line-height should
increase the block size of the line, but that setting should not effect
their own size.
In addition to the new passes there are some new failures

When a box has overflow, any floats placed in that box will lower the
float ceiling into the overflow. If no float is placed in the box
though, the ceiling should be the block position where the overflow
starts. We already know where this is, because we might be passing a
negative value for the new block position after processing a box
(content_size - actual_size would be negative). This negative value
never raises the ceiling though since a maximum is used.
In the case that there is overflow, this change allows raising the
ceiling, but never passed the lowest float. This necessitates keeping
two values for the ceiling: one for floats and one for non-floats.
Fixes#30304.
