This is just a refactor in the right direction. Eventual goal is:
* All inherited properties use ArcSlice<>.
* All reset properties use OwnedSlice<> (or ThinVec<>).
No conversion happens at all, so we can remove all that glue, and also
compute_iter and co.
Of course there's work to do, but this is a step towards that.

This avoids the expensive conversion, and cleans up a bunch.
Further cleanup is possible, just not done yet to avoid growing the patch even
more.

We destroy them manually, so it's the right thing to do.
This allows us to not run destructors of any members of nsStyle*, which in turn allows us to:
* Remove the hack that replaced all nsStrings for nsStringReprs.
* Remove ns{,C}StringRepr (followup)
* Add members with destructors to the style structs (you see where I'm going :)).

As I said over bug 1549593, the eventual goal is to use ArcSlice in all
inherited properties. But this seemed like a good first candidate that doesn't
require me to move around a lot more code, since we were already using cbindgen
for the path commands.

We could make the header PhantomData or something, but then we wouldn't be able
to bind to C++, since C++ doesn't have ZSTs. So add a canary instead to add a
runtime check of stuff being sane.

This enables destructors for tagged unions in cbindgen, implemented in:
* https://github.com/eqrion/cbindgen/pull/333
Which allow us to properly generate a destructor for the cbindgen-generated
StyleBasicShape (which now contains an OwnedSlice).
For now, we still use the glue code to go from Box<BasicShape> to
UniquePtr<BasicShape>. But that will change in the future when we generate even
more stuff and remove all the glue.
I could add support for copy-constructor generation to cbindgen for tagged
enums, but I'm not sure if it'll end up being needed, and copy-constructing
unions in C++ is always very tricky.

Passing these by value won't be ok of course, but that's fine.
I plan to combine this with https://github.com/eqrion/cbindgen/pull/333 to
actually be able to share representation for ~all the things, this is just the
first bit.
Box<T>, Atom and Arc<T> will be much easier since cbindgen can understand them
without issues.
It's boxed slices the only ones I should need something like this. I could avoid
it if I rely on Rust's internal representation, which we can per [1], but then I
need to teach cbindgen all about slices, which is generally hard, I think.

The change from [T; 1] to [T; 0] shouldn't change behavior since they have the
right alignment and we never poke at that particular array, but feels more
correct to avoid creating types that point to uninitialized data or outside of
their allocation, now that we allow empty slices.

test_css_parse_error_smoketest.html is great to assert that something _gets_
reported, but not that it doesn't :)

Also, buffer the errors, since we're going to want to look at the whole
declaration block to skip reporting them.
This shouldn't change behavior, just moves some work to the caller, and defers a
bit the work so that it happens only when error reporting is enabled.

The initial value for this is indeed `none` (and thus empty). The Rust code was
confused.
This property is disabled by default these days, and I think the
get_initial_value() function, which is what could get confused, is not called
for this property, so I think this shouldn't be observable.

Fixes#23227
This cherry-picks https://github.com/servo/servo/pull/23228.
Converting the NS_STYLE_BORDER definitions in to enumerated classes as
per bug 1277133.
The original constants broke the convention used by the rest of the
definitions as the CSS property being described is `border-collapse`,
so corrections were made with the migration to the enumerated class.
