stylo: support background-size and corner gradients
Forgot to fix this in the midst of all other things fixed in #12945
<s>(not yet tested, need to figure out how to test bg-size with gradients)</s>

Expressions with percentages may be negative or positive at computed value time.
So, we can only clamp lengths at computed value time, which is what the other
browsers do.
Don't use mem::uninitialized() for making calc values
We had code relying on `nsStyleCoord::set()` being leaky (like it was
before we patched up the calc bindings). Added `nsStyleCoord::null()` for
this use case since it's not possible to construct directly anymore.

Update WR + shaders (switch to untyped UBO for CI).
This makes WR startup time significantly faster on Linux, by working around a slow path in the shader compiler.

Add lots of Arc’s in style, and prepare for using DOMRefCell
<!-- Please describe your changes on the following line: -->
`DOMRefCell` usage is not there year because of thread-safety questions, but I have this much already that I’d like to land before it bitrots.

a script query.
This will, rather unfortunately, mean that we might repaint two times if we've
deferred a paint, then get an out-of-band reflow. Still seemed better than not
suppressing paints at all.
Fixes#13131
