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 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.

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.

* Obey min and max properties when computing main size of column flex
When laying out a column flex container with an auto preferred main size,

However, we weren't clamping this amount between the min and max sizes.

* Improve performance of flex column layouts by caching
We were already using a cache for layout_for_block_content_size(), but
we were only storing the intrinsic block size. Thus when laying out the
flex items for real, we would perform new layouts, triggering an
exponential complexity in case of nested flexboxes.
Now we cache the entire layout result so that we can avoid doing the
work again.
This improves the results of flexbox-deeply-nested-column-flow.html
(a Blink perf test) from ~40 runs/second to ~500 runs/second on my PC.

`AbsoluteAxisSolver::solve()` would compute, among other things, the
position of the absolute positioned element if it had start alignment.
Then, `AbsoluteAxisSolver::origin_for_alignment_or_justification()`
could optionally opt into modifying that alignment if needed.
This was quite convoluted and not easy to follow. It's simpler to not
compute the position in `AbsoluteAxisSolver::solve()`, and instead do it
always in `AbsoluteAxisSolver::origin_for_alignment_or_justification()`,
which I'm renaming to `AbsoluteAxisSolver::origin_for_margin_box()`
because it aligns the margin box of the abspos within its alignment
container.
Then the `Anchor` struct becomes useless and can be removed.
Signed-off-by: Oriol Brufau <obrufau@igalia.com>
The containing block for the static position of an absolutely positioned
element in flex layout is established by the flex container. However, if
the flex container has static position, the actual containing block will
be established by another ancestor.
If the flex container and the containing block have different directions,
the static position needs especial handling when aligning the abspos.
We were already trying to do so with the `flip_anchor` flag, but there
were bugs.

- Avoid computing the inline content sizes if the result isn't needed.
