Apply some clang-tidy suggestions while I was going through the
ServoStyleConstsInlines while at it.
Remove one 0x test because it's tested on the same test and causes a
harness error.

This unveils an issue with image-set() tests, which expect 0x to not
parse (inconsistently with media queries).
Fix the test, since the spec doesn't restrict the range of <resolution>
values (and more importantly, it shouldn't allow open ranges).

This implements the basic image-set notation without the format()
function (for simplicity).
There's a remaining serialization issue (we should probably skip 1x
resolutions), but that's fine for now, I'll address this in a follow-up
when the feature is testable.
The intention is to do the image selection at computed value time
(keeping a selected index or such), but same, follow-up.
This also fixes an issue where the cors-mode for -moz-image-rect and
cross-fade() was getting ignored when parsing.
