Not super-proud of this one, but it's the easiest way I could think of.
The changeset looks bigger than what it is, because while at it I've rewrapped a
fair amount of functions around to use proper block indentation.
Alternatives are parameterizing Stylist by <E>, which is not fun, or moving the
concrete element from layout_thread to layout, but that implies layout depending
on script, which isn't fun either.
Other alternative is implementing an empty enum and making anon boxes work on
it. It has the advantage of removing the annoying type parameter, but the
disadvantage of instantiating `cascade` twice, which isn't great, and having to
maintain all the boilerplate of a `TElement` implementation that just does
nothing.
Do not leave space below baseline when it is not needed (i.e.there is…
… no text)
This is my first layout fix and a naive approach to fix#18831.

It used to be the case that MatchingContext was immutable and thus we didn't
care to have accessors.
This is no longer true, so let's make this code a bit nicer.
Implement Element::has_css_layout_box()
r? emilio
Here's my initial attempt to fix#19430. It seems surprisingly simple so I am wondering whether I have missed something! (Or maybe it just actually is quite simple...)
Some things I am unsure about:
1. The spec seems vague about what a [CSS layout box](https://drafts.csswg.org/cssom-view/#css-layout-box) actually is. Indeed it says: "The terms CSS layout box and SVG layout box are not currently defined by CSS or SVG."
2. One thing the spec *does* say explicitly is "For the purpose of the requirements in this specification, elements that have a computed value of the display property that is table-column or table-column-group must be considered to have an associated CSS layout box (the column or column group, respectively)." I am unclear about the relevance of this, since [overflow does not apply](https://drafts.csswg.org/css-overflow-3/#overflow-properties) to an [internal table element](https://drafts.csswg.org/css-display-3/#layout-specific-display). Therefore I haven't done anything about this explicitly, but maybe I'm missing some nuance.

Remove gecko-media dependency
The effort to import Gecko's media stack into Servo has been canceled, so I am removing the bits of code from gecko-media that we added to Servo.

Calling scroll() on an element which is not rendered (by a parent with
display: none) would previously cause a crash. In fact, we should
terminate the algorithm
[https://drafts.csswg.org/cssom-view/#dom-element-scroll] at step 10 in
this situation.
The fix hinges on implementing Element::has_css_layout_box() correctly,
rather than just returning true in all cases as we did previously.
Fixes#19430.
It makes no sense to pass a custom base size of zero in presence of rem, ex, or
ch units.
