Use raw pointers instead of transmute for UnsafeFlow
This makes the code depend a bit less on rustc implementation details.

Only generate structs file for the current build
This PR changes build_gecko.rs to only generate the `structs.rs` for the current build (rather than both), depending on whether `gecko_debug` feature is set.
The in-tree files are switched to use the previous release one, because that's what we currently use for stylo test and it is in general what we really care about. For this change, `gecko_debug` mode is removed from Servo CI (in `build-geckolib`) with the assumption that people general do that build locally for stylo development, so it is less likely to be broken than release.

style: Iterate in the expected order in the custom_properties module.
In #18745, I replaced a few manual iterations over `index` with the iterator,
and it changed the behavior of `layout/style/test/test_variables_order.html`,
since it turns out that the iterator iterates right to left.
I think this is just an accident that happened due to inconsistencies in how we
were iterating over it, and that our behavior was inconsistent (since we
iterated rtl in some cases, but ltr in others seems like it'd be inconsistent
depending on the depth of the tree and different stuff).
This brings back the expected behavior again, and ensures we iterate over a
consistent order every time.

Update web-platform-tests
This updates web-platform-tests to a46616a5b18e. It also removes our local copy of wptrunner in favour of the upstream one that we can modify and sync more easily. Carried from #17416.

style: Use the flattened tree parent to find the closest non-nac ancestor of an element.
This only matters for document level NAC like canvas custom content, in which
case otherwise we inherit from the document element (which is wrong).

Bug: 1405635
If the first test selected by a testrunner thread had a CRASH expectation,
the testrunner believed that it needed to restart and would never actually
get around to running the test.
Change resolution queries to compare in unconverted dppx units.

Fix the test count in the WPT grouping_formatter
The internal WPT API seems to have changed again, so we must revert the
previous change here to get the correct test count.
