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.

Harden assert for creating atom from raw pointer
One of Stylo's common assertion turns out to be from having a null Atom (see [Gecko 1385925 bug comment 7](https://bugzilla.mozilla.org/show_bug.cgi?id=1385925#c7)). It would be helpful if we can catch this kind of crash earlier via a release-assertion.
This may regress performance to some extent which I'm not sure. But we can probably have it there for diagnosis for now, and remove later.

layout: Stop call normal block size assignment for flex container
No need to call the `assign_block_size_block_base()` method of normal block in flex.rs since it is implemented for CSS2.

enable antialiasing by default
This is not a problem for regular Servo because these values are toggled when the command line is parsed. But it's not the case when embedding Servo.

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: 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.
