This might make caching these values a bit easier in the future.
Correcting the visibility of `ContainingBlock` also exposed some new
rustc and clippy warnings that are fixed here.

The `pending reflow` concept isn't necessary now that *update the
rendering* is taking care of triggering reflows at the correct time.
`Window::reflow` already avoids reflows if the page is not dirty, so
pending reflows is now just an extraneous check as long as *update the
rendering* runs properly.
This change also removes some explicit reflows, which now wait until the
appropriate moment during *update the rendering*. This should remove
some extra reflows that are not necessary.
Servo needs some way to track that resizing the web view needs to
re-layout due to the initial containing block changing. Move handling
of `Document::needs_paint` to the script thread and use this, expanding
the rustdoc to explain what it is for a bit more clearly.

Consider this testcase:
```html
<canvas style="aspect-ratio: 1; height: stretch; background: cyan"
width="200" height="100"></canvas>
```
To compute the intrinsic inline sizes we were treating `height: stretch`
as the natural height (100px) and then transferring that to the inline
axis through the preferred aspect ratio. So the element was 100px wide.
However, an indefinite `stretch` should be treated as an automatic size,
which wouldn't be transferred to the inline axis.
The fix actually makes the code slightly simpler.

Instead run *update the rendering* at the end of every process of
gathering messages sent to the `ScriptThread`. This ensures that the
thread is in a consistent state when the update is finally run and
prevents running more than one instance of *update the rendering* per
spin of the message loop.
In addition:
- Move the *run the resize steps* implementation to `Window` and ensure
that the realm is active when it is run.
- Profile the queueing of the resize message instead of handling it. I
think this makes more sense as the profiling seems to be targeting
message handling and not *update the rendering*. Additionally, it's
difficult to profile from the context of `Window`.

Add a trace for the `select!` macro, so
that we can easily identify the amount of
time we are blocked in the trace
A different option might be to just skip
tracing the `handle_request` function entirely,
since it contains almost nothing interesting.

This patch switches servo to use `uv` for both installing a pinned
Python version as well as installing the dependency packages using
`uv`'s pip compatible interface. It also introduces a new 'composite'
GitHub action to setup python in the different CI workflows.
There is no support for externally managed python installations and
virtual environments. These could be added in the future.

This changes fixes two issues:
1. A reflow of all `Document`s currently done unconditionally after
receving IPC messages in the `ScriptThread`. Reflowing without first
updating the animation timeline can lead to transitions finshing as
soon as they start (because it looks like time advancement is
measaured between calls to `update-the-rendering`).
2. Fix an issue where not all `Pipeline`s were updated during *update
the rendering*. The previous code only took into account top level
frames and their children. It's not guaranteed that a particular
`ScriptThread` is managing any top level frames, depending on the
origens of those frames. We should update the rendering of those
non-top-level iframes regardless.
The new code attempts to order the frames according to the
specification as much as possible without knowing the entire frame
tree, without skipping any documents managed by the `ScriptThread` in
question.
In addition, `Documents` is pulled out the `script_thread.rs` and
renamed to `DocumentCollection`.

Add a new struct `LayoutBoxBase`, that will be used throughout the box
tree. The idea of this struct is that we have a place to consistently
store common layout information (style and node information) and also to
cache layout results such as content sizes (inline and maybe later box
sizes) and eventually layout results.
In addition to the addition of this struct,
`IndependentFormattingContext` is flattened slightly so that it directly
holds the contents of both replaced and non-replaced elements.
This is only added to independent formatting contexts, but will later be
added to all block containers as well.

Add a preference to limit the size of the webrender threadpool.
Note: WebRender by default calls hooks which register the threads with
a profiler instance that the embedder can register with webrender.
Servo currently doesn't register such a profiler with webrender,
but in the future we might also want to profile the
webrender threadpool.

Mach is currently failing bootstrap and building if the Python version
is greater than 3.12. This is because wpt does not support 3.13 yet.
This causes confusion for people running recent distros that ship 3.13
by default.
I changed the logic so that mach checks both the minimum and the maximum
supported versions of Python instead of just checking the minimum. It
will now also tell you which maximum version is supported.
I also updated the README.md to specify the supported Python versions
so that people don't accidentally install the wrong version.

Before, `update_the_rendering()` would update all animations for all
Documents once per-Document. Apart from being generally wrong, the
specification says this should be done once per-Document. This
theoretically means that `update_the_rendering()` is just doing less
work every time it runs.
In addition:
- Don't redirty animations nodes when running rAF callbacks. They
should already be dirty when animations are updated.
- Perform a microtask checkpoint while updating animations as dictacted
by the specification.
- Update comments to reflect the specification text.
