This moves white space collapse to right before breaking and shaping
happens, which is more similar to what happens in legacy layout. This is
the first step toward making this procedure more efficient (avoiding
string copies) and also implementing support for `text-transform`.

In layout2020, 'list-style-position' is disabled behind a pref, so the
list_style_position field is an Option.
The serialization of the 'list-style' shorthand wasn't correctly
handling the case of it being None.
This adds an initial implementation of font fallback, on part with the
one used in legacy layout. There are still issues. For instance, font
matching is done per unicode character rather than based on graphemes or
the shape first approach of Chrome. The idea is that these changes can
be made later.

This implements a very naive row height allocation approach. It has just
enough to implement `vertical-align` in table cells. Rowspanned cells
get enough space for their content, with the extra space necessary being
allocated to the last row. There's still a lot missing here, including
proper distribution of row height to rowspanned cells.

This should fix issues that we have with Float16 support on newer LLVM.
This also updates style, in order to remove the duplicate version of
bindgen. We will soon be able to manage updates to style more
consistently.
For example,
style.cssText = "margin: 1px 2px 3px 4px";
[...style];
will now be
["margin-top", "margin-right", "margin-bottom", "margin-left"]
instead of
["1px", "2px", "3px", "4px"]
Instead of using the border widths from the style, use the ones recorded
by the `BoxFragment`. This is necessary because inline layout can
override these border widths during fragmentation. For instance, when a
box is split across two lines only one fragment should have an inline
start border.
The crash when loading servo.org happens in the JIT code
emitted by SM's CacheIRCompiler to invoke the VM function
`ProxyGetPropertyByValue`.
To disable this code path, it is not sufficient to disable
just the baseline JIT (which exposed in servo under the
pref `js.baseline.enabled`) but also the baseline
interpreter which is controlled by a different flag in SM.
This PR disables renames the `js.baseline.enabled` pref in
Servo to `js.baseline_jit.enabled` and introduces a new
pref `js.baseline_interpreter.enabled` that controls the
baseline interpreter.

Instead of tracking justification opportunities during line layout, wait
until the line is about to be laid out and justification is about
happen. This makes the logic for tracking justification opportunities
simpler. In particular, we no longer have to carefully adjust them when
trimming whitespace. Additionally, this avoids a bit of work unless
justification is turned on.
This also includes a small cleanup of the justification code.
This change starts collecting the starting baseline set for fragments,
which is necessary for some layout modes (flex and tables, namely) as
well as being important for the implementation of `align-items`. In
addition, it converts baseline measurement to use `Au` everywhere.

Instead of making the client set up GL video decoding, have this done
inside libservo. The details necessary for decoding are fetched via
Surfman now. This also removes the setup for the context on Android --
which has no GStreamer support now anyway. In the future, this could be
enabled, but should likely be done using Surfman, instead of passing on
all these details manually.

This is a small cleanup that moves and renames this class. The rename is
simply because we are exposing a lot about the details of Servo's
rendering in the API and it makes sense to start thinking about
abstracting that away a bit.
This also moves the struct to `gfx`, which does have an effect on
Servo's dependency graph. This adds a new dependency on gfx to
`compositing`, but `compositing` had a transitive dependency on
gfx before through `canvas`.

Shape text during InlineFormattingContext construction rather than doing
it twice during fragment tree construction. This is a step on the way
toward proper font fallback.
This also moves all `TextRun` related code into `text_run.rs` to try to
trim down the size of `inline.rs`.
