Assert fail #18439
<!-- Please describe your changes on the following line: -->
This PR addresses #18439 by removing an assert statement that forces a panic whenever `LoadBlocker` is dropped during a GC sweep and receives a `None` `SCRIPT_THREAD_ROOT` value from `mark_document_with_no_blocked_loads()`. Instead of panicking on the assert, we remove it and let the None value pass silently.

- removed unused import in document_loader.rs
- limit unsafe block in mark_document_with_no_blocked_loads in script_thread.rs
- changed name of if let value to load in Drop for LoadBlocker in document_loader.rs
Update wpt metadata to show the new passes.
Add one test as crashing since currently passing an @import rule to insertRule
leads to "Expected a stylesheet loader for @import"
Fixes#23025
Add Gecko reftests, which are failing with gfx-hal backend
<!-- Please describe your changes on the following line: -->
Since the focus of the Szeged team will shift to Servo from Gecko, we would like to add some reftests from Gecko which are failing with the gfx-rs backend.
Last year we had pretty good results with Servo css tests: https://github.com/szeged/webrender/issues/173#issuecomment-415373702.
On the Gecko side we had more failing tests, and it would be nice to have a subset of those in Servo, even tough some of them fails on the Servo side.

The way the copy-on-write stuff works, and the way that we have to apply
properties from most specific to less specific guarantees that always that we're
going to inherit an inherited property, or reset a reset property, we have
already the right value on the style.
Revert relies on that, so there doesn't seem to be a reason to not use that fact
more often and skip useless work earlier.
Font-size is still special of course... I think I have a way to move the
specialness outside of the style, but piece by piece.

The only fishy bit is the animation stuff. In particular, there are two places
where we just mint the revert behavior:
* When serializing web-animations keyframes (the custom properties stuff in
declaration_block.rs). That codepath is already not sound and I wanted to
get rid of it in bug 1501530, but what do I know.
* When getting an animation value from a property declaration. At that point
we no longer have the CSS rules that apply to the element to compute the
right revert value handy. It'd also use the wrong style anyway, I think,
given the way StyleBuilder::for_animation works.
We _could_ probably get them out of somewhere, but it seems like a whole lot
of code reinventing the wheel which is probably not useful, and that Blink
and WebKit just cannot implement either since they don't have a rule tree,
so it just doesn't seem worth the churn.
The custom properties code looks a bit different in order to minimize hash
lookups in the common case. FWIW, `revert` for custom properties doesn't seem
very useful either, but oh well.

We can get back the fancy flag syntax as soon as we get C++17 inline variables,
which I sent an email to dev-platform@ about, with no reply.

I feel a bit weird for using LenghtPercentageOrAuto to implement LengthOrAuto,
but I don't think much other code will use it so it seemed a bit better to me.

We really only have two sets of prefs, one for chrome-like documents
(stuff in chrome docshells + chrome-origin images), and one for the rest.

This also adopts the resolution from [1] while at it, making letter-spacing
compute to a length, serializing 0 to normal rather than keeping normal in the
computed value, which matches every other engine.
This removes the SMIL tests for percentages from letter-spacing since
letter-spacing does in fact not support percentages, so they were passing just
by chance.
