webgl: premultiplication, y flipping, and format conversion
<!-- Please describe your changes on the following line: -->
This series implements a bunch of the texture unpack path features for WebGL. There are known issues with big-endian systems noted in the comments, but I don't know of a clean way to cast from `Vec<u16>` to `Vec<u8>` (which, if we had one, would make this code much cleaner anyway).

Issue #15017: Properly handle and report network errors on page loads.
<!-- Please describe your changes on the following line: -->
This patch fixes how network errors are handled during page loads: they would not be reported and cause crashes before, and do not anymore.

Add support for more @font-face descriptors
<!-- Please describe your changes on the following line: -->
Part of https://bugzilla.mozilla.org/show_bug.cgi?id=1290237. I’ll add conversions to `nsCSSValue` separately because that requires new C++ functions in the stylo repository.

Remove the 29 byte limitation, when requesting bluetooth devices
<!-- Please describe your changes on the following line: -->
Remove the 29 byte limit when calling `requestDevice` using a `name` or `namePrefix`. The following discussion is about this by the specification writers: https://bugs.chromium.org/p/chromium/issues/detail?id=653718.
Related tests also got removed.

Make additional properties be reset by the 'font' shorthand.
A number of properties are supposed to be reset to initial values by the
'font' shorthand. This does so for all such properties that Servo
currently supports (conditional on when they're supported).
Fixes#15033.
It's not clear to me that the use of <code>None</code> is correct for resetting to initial values, but it seems to match what at least some other shorthands do (I think I was looking at the code for border), and it appears to fix the tests as expected. I haven't probed into it more than that.

This has test coverage when running stylo. In particular, it fixes a bunch of sets of mochitest failures in layout/style/test/test_value_storage.html, with the set for each value of the 'font' shorthand listed in property_database.js looking like:
```

I'm not sure if separate Servo test coverage is needed.

We need to create CSS animations that have empty keyframe or keyframes
which have only invalid properties or non-animatable properties to fire
animation events for such animations.
Styling was correct because of the explicit dirtiness, but still not fun.
Some things, like dynamic updates to with things like [style~="color"] ~ foo
selectors, were pretty broken, because we didn't take snapshots of those
attributes.
