Manage `<iframe>` size updates in `Window`. In addition to removing
duplicated code, this will allow setting `<iframe>` sizes synchronously
on child `Pipeline`s of the same origin in the script process in a
followup change. The goal is remove flakiness from `<iframe>` sizing.

This eliminates the way that crossbeam channels are used to send layout
results back to script, which should increase the efficiency of layout.
If asynchronous layout is re-established it can be written as a layer on
top of the layout interface, that way layout doesn't have to know so
many details of how the asynchronocity works.
Renames:
- `ScriptReflow` to `ReflowRequest`: Script is the only thing that
requests reflow.
- `ReflowComplete` to `ReflowResult`

These all happen now in *update the rendering*, typically after the
message that triggered this code is processed, though in two cases
reflow needs to be triggered explicitly. This makes `ReflowReason`
redundant though perhaps `ReflowCondition` can be expanded later to give
more insight into why the page is dirty.
- Handling of the "reflow timer" concept has been explained a bit more via
data structures and rustdoc comments.
- Theme changes are cleaned up a little to simplify what happens during
reflow and to avoid unecessary reflows when the theme doesn't change.
Notably, layout queries and scrolling still trigger normal reflows and
don't update the rendering. This needs more investigation as it's
unclear to me currently whether or not they should update the rendering
and simply delay event dispatch or only reflow.
In general, this is a simplfication of the code.
Fixes#31871.

A rendering opportunity is now unconditionally triggered by handling IPC
messages in the `ScriptThread`, unless animations are running in which
case it's driven by the compositor. We can now remove calls to
`note_rendering_opportunity` and `rendering_opportunity`.
There is one tricky case, which is when a promise completion during a
microtask checkpoint dirties the page again. In this case we need to
trigger a new rendering opportunity, unless animations are running. In
a followup change, when not driven by the compositor, rendering
opportunities will be driven by a timed task, meaning we can remove this
workaround.

This removes two explicit calls to reflow to detect rAFs that do not
modify the DOM and to trigger reflows when the page isn't dirty. This
can cause extra reflows, especially when animations are running. This
change removes them, relying on *update the rendering* to properly
trigger reflows, shortly after running rAF callbacks and after
animations are updated.

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.

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`.

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`.

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.

This is unfortuante, but it's the only way to stop making Stylo's
`malloc_size_of` depend on so many of Servo's dependencies. This is an
important step on the way toward releasing Stylo as standalone software.
When possible, we defer to the implementation of `MallocSizeOf` that is
in the base class.
One benefit of this change is that we start properly measure the size of
WebRender types, which before were always set to zero.
In addition the `Measurable` class is removed in favor of simply
manually implementing `MallocSizeOf`, which doesn't require
uncomfortably modifying the shape of data structures.
