Stylo is currently skipping parent display-based style fixups for all NAC,
whereas we probably only want to do this for NAC roots.
In this patch, we ensure that we skip it for NAC roots, and pseudo-elements,
but not other NAC.
stylo: Bug 1390039 - Implement compute_distance for mismatched transform lists.
Implement ComputeSquaredDistance for mismatched transform lists.
In order to do this, we have to convert a transform list into a 3d matrix,
so I move the code from layout module into style module for reusing it.

- [X] These changes fix [Bug 1390039](https://bugzilla.mozilla.org/show_bug.cgi?id=1390039).
- [X] These changes do not require tests because this is a Gecko feature and I add many tests in Gecko already.

style: Avoid scanning the longhand id twice in the fast path of PropertyDeclarationBlock::parse_common
This makes the overhead of this function much lower according to `perf`.
And in general makes sense, removing overhead from the fast path.

Use cssparser's new_with_line_number_offset
cssparser provides a way to set the initial line number on a
ParserInput. This patch changes servo to use this facility, rather than
reimplement the same functionality itself.

style: Remove uninlineable function in PropertyDeclarationIterator.
That literally made no sense, and is probably leftover from where we passed Map
directly there.

Prioritize parsing non-custom property names.
This should cause a slight improvement in the common case where we are parsing non-custom property names.

style: Don't look for viewport units in stylesheets.
Use whether we've computed any viewport unit instead.
This is more accurate (we avoid restyling unnecessarily if we've found anything
ever on the stylesheet, but that hasn't matched).
This has the benefit of also matching Gecko, and simplify some code and
fishyness around, and also hopefully speeding up stylesheet parsing.
