A `<video>` element with no source won't have a natural aspect ratio,
but `aspect-ratio: auto` should still fall back to a ratio of 300/150.
`used_size_as_if_inline_element_from_content_box_sizes()` was already
handling this, but other consumers of `preferred_aspect_ratio()` were
wrong. In particular, this resulted in a 0px wide inline-block:
```html
<div style="display: inline-block; border: solid">
<video style="height: 100px; background: cyan"></video>
</div>
```
So this patch moves the fallback into `preferred_aspect_ratio()`.

We were following CSS2, which didn't handle `aspect-ratio`.
This patch simplifies the logic and handles it correctly.
Unfortunately this makes 2 tests fail, but I'm pretty sure they aren't
spec-compliant. I'm leaving them as-is for now since they are part of
interop-2021, and Gecko, Blink and WebKit pass them (because of some
non-interoperable incorrect behaviors).
I'm adding a new test that is fully passed by Servo and WebKit.

Anonymous blocks have `height: auto`, so children with a percentage
`height` were considered to have an indefinite height.
However, anonymous blocks need to be skipped for percentage resolution,
so the percentages may actually be definite.

In particular, this takes into account that flex items may be stretched,
and if they have an aspect ratio, we ma6y need to convert the stretched
size through the ratio.

We were only handling the aspect ratio of a replaced element when
computing its min/max-content contribution, but not when computing
the min/max-content size. Now both cases will take it into account.
Signed-off-by: Oriol Brufau <obrufau@igalia.com>
When computing the min-content or max-content size of an element we
need to ignore `inline-size`, `min-inline-size` and `max-inline-size`.
However, we should take the block-axis sizing properties into account.
That's because the contents could have percentages depending on them,
which can then affect their inline size via an aspect ratio.
Therefore, this patch adds `IndefiniteContainingBlock`, which is similar
to `ContainingBlock`, but it allows an indefinite inline-size. This
struct is then passed arround during intrinsic sizing.
More refinement will be needed in follow-up patches in order to fully
address the problem.

According to HTML, the `width` and `height` attributes should only set
the natural sizes and the aspect ratio.
The `width` and `height` properties should stay as `initial` by default.

This adds supports for right-to-left text assigning bidi levels to all
line items when necessary. This includes support for the `dir` attribute
as well as corresponding CSS properties like `unicode-bidi`. It only
implements right-to-left rendering for inline layout at the moment and
doesn't include support for `dir=auto`. Because of missing features,
this causes quite a few tests to start failing, as references become
incorrect due to right-to-left rendering being active in some cases,
but not others (before it didn't exist at all).
Analysis of most of the new failures:
```
- /css/css-flexbox/gap-001-rtl.html
/css/css-flexbox/gap-004-rtl.html
- Require implementing BiDi in Flexbox, because the start and
end inline margins are opposite the order of items.
- /css/CSS2/bidi-text/direction-applies-to-*.xht
/css/CSS2/bidi-text/direction-applies-to-002.xht
/css/CSS2/bidi-text/direction-applies-to-003.xht
/css/CSS2/bidi-text/direction-applies-to-004.xht
- Broken due to a bug in tables, not allocating the
right amount of width for a column.
- /css/css-lists/inline-list.html
- This fails because we wrongly insert a soft wrap opportunity between the
start of an inline box and its first content.
- /css/css-text/bidi/bidi-lines-001.html
/css/css-text/bidi/bidi-lines-002.html
/css/CSS2/text/bidi-flag-emoji.html
- We do not fully support unicode-bidi: plaintext
- /css/css-text/text-align/text-align-end-010.html
/css/css-text/text-align/text-align-justify-006.html
/css/css-text/text-align/text-align-start-010.html
/html/dom/elements/global-attributes/*
- We do not support dir=auto yet.
- /css/css-text/white-space/tab-bidi-001.html
- Servo doesn't support tab stops
- /css/CSS2/positioning/abspos-block-level-001.html
/css/css-text/word-break/word-break-normal-ar-000.html
- Do not yet support RTL layout in block
- /css/css-text/white-space/pre-wrap-018.html
- Even in RTL contexts, spaces at the end of the line must hang and
not be reordered
- /css/css-text/white-space/trailing-space-and-text-alignment-rtl-002.html
- We are letting spaces hang with white-space: pre, but they shouldn't
hang.
