Skip some parts of image-layer shorthands when they are initial
To make it closer to Gecko's serialization algorithm.
Neither Servo nor Gecko currently perfectly matches the spec. Gecko has some test for this, but I don't think that's sufficient, so I'll add some later if there aren't any in Servo.

stylo: Implement gecko glue for font-language-override.
To be aligned with the implementation from Gecko side, we parse
font-language-override as Normal keyword or String. Then, we compute
and store it as a u32. So, as to the stylo glue, we can just pass the
u32 to Gecko.
The extra crate, byteorder, is used to simplify the computing and
serialization.
Since we now implement font-language-override for Gecko, we can remove
the additional branches for font-language-override in font shorthand.

Add full parsing/serialization for mask-repeat and background-repeat
I implemented full parsing and serialization for the mask-repeat and background-repeat style properties. I think some more tests are required but I'm not what I'm missing. I'd appreciate some direction.
I also had to modify some layout code to get my changes to compile. As a result, background-repeat should work individually in both directions now too.

It should be checking the value of the 'writing-mode' property, not the value of
the "writing mode" concept. The latter is influenced by other properties like
'direction' and whatnot. That was causing this code to convert inlines to
inline-blocks if they just had a different direction from their parent, which is
not correct
Make writing-mode affect computed display
<!-- Please describe your changes on the following line: -->
The first manual test-case in #15754 passes now, but the second test-case still renders "Text" horizontally, which is apparently because of servo's experimental support for writing-mode.

It's a bit unfortunate the use separate implementations of SpecifiedUrl for Servo
and Gecko, but they're different enough at this point that I don't think it really
makes sense to try to share everything. Splitting them out has some nice
simplifications as well.
I recognize that there's still some potential correctness issues for Servo using
the resolved URI in various places where the original URI may be the right thing,
but I've got too much on my plate to look into that for now.
