This change adds support for `position: relative` to table `<caption>`.
In addition to adjusting their position according to inset values, table
captions must also establish containing blocks for descendants that are
absolutely positioned.

This also makes a couple small improvements:
- Rename `IntrinsicSizes` to `NaturalSizes` which reflects more
modern spec language.
- Move the conversion of Stylo's `ImageRendering` to WebRender's
version to a `ToWebRender` trait implementation.

* The CustomEvent constructor is infallible

If we encountered a preserved line break after some whitespace, we were
including the space in the max-content size of the following line.
So just like `line_break_opportunity()` was already clearing
`self.pending_whitespace.min_content`, `forced_line_break()` needs to
clear `self.pending_whitespace.max_content` too.
Also some cosmetic refactoring.

<col> and <colgroup> elements can be used to create extra columns that
have no cell. We were removing these columns and column groups, but in
general we shouldn't do that.
Now we will only remove them if the table has no row nor row group.

A table cell with `width: auto` in fixed layout will now have an outer
min-content width of zero, even if it has borders or padding. In a way,
this is like allowing the content-box width to become negative.

When computing the ascent and descent in an inline formatting context,
we weren't taking into account that app units have precision limitations.
Therefore, in some cases we were getting a line height that was slightly
taller than the value specified in `line-height`.

On tables, we need to treat an overflow value of `scroll` or `auto` as
`visible`. Both `scroll` or `auto` are scrollable, which implies that
the other axis must also have a scrollable value.
Therefore, when we make the value behave as the non-scrollable `visible`,
we need to adjust the other axis too.
The previous logic was checking `is_scrollable()` but that wasn't
necessary, since computed values must have the same scrollability.

* libservo: Improve finding python
Servo is built in a virtual environment, which sets `VIRTUAL_ENV` to
the base path of the venv.
PYTHON3 is only set if mach or the user set it.
Additional changes:
- Use Path / var_os for Paths instead of strings.
In General using Path APIs is preferable, since in rare cases
valid paths may not be valid utf-8.
- Don't search for python 3.8 anymore, since
we require a newer version anyway.
- Don't add the .exe suffix anymore, since
Command::new() will take care of that.

* Fix finding venv python on windows
- On Windows the venv scripts and python binaries are in the
`Scripts` subdirectory instead of `bin`.
- We shouldn't check if the executable in the venv binary dir
exists, since the actual file could have a `.exe` suffix.
We don't need to consider the `.exe` suffix for the filename,
since `Command` will handle that for us.
We also anyway check the validity of the candidate file, by
running `$candidate --version`.

This change removes the `effective_writing_mode` concept and tries to
properly implement right-to-left layout support for all non-inline
writing modes. In general, what needs to happen is that rectangles
need to be converted to physical rectangles using the containing block.
A right-to-left rectangle's inline start is on the right physical side
of the containing block. Likewise a positive inline offset in
right-to-left text is a negative physical one.
The implementation here is pretty good for most layout modes, but floats
are still a bit in process. Currently, floats are processed in the
logical layout of the block container, but there still might be issues
with float interaction with mixed RTL and LTR.
While this does move us closer to supporting vertical writing modes,
this is still unsupported.
New failures:
- Vertical writing mode not supported:
- `/css/CSS2/floats/floats-placement-vertical-001b.xht`
- `/css/CSS2/floats/floats-placement-vertical-001c.xht`
- Absolutes inlines should avoid floats (#33323)
- `/css/css-position/position-absolute-dynamic-static-position-floats-004.html`
- No support for grid
- `/css/css-align/self-alignment/self-align-safe-unsafe-grid-003.html`
- `/css/css-position/static-position/inline-level-absolute-in-block-level-context-009.html`
- `/css/css-position/static-position/inline-level-absolute-in-block-level-context-010.html`
- Cannot reproduce these locally on any platform. Very mysterious:
- `/css/css-tables/row-group-margin-border-padding.html`
- `/css/css-tables/row-margin-border-padding.html`
- Exposes bugs we have related to hanging whitespace in preserved
whitespace inlines:
