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.

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).

nsTFixedString<T> is only used as a base class for nsTAutoStringN<T, N>, so
this patch merges the former into the latter, cutting some code and simplifying
the string class hierarchy.
Because the "Fixed" name is now gone, the patch also renames
StringDataFlags::FIXED as INLINE and ClassDataFlags::FIXED as INLINE.
The patch also removes nsFixed[C]String and ns_auto_[c]string! from Rust code
because nsAutoString can't be implemented directly in Rust due to its move
semantics. There were only two uses of ns_auto_string! outside of tests so this
seems like a minor loss.
