In order to test its parsing and serialization, we expose it but protect
it behind a pref.
Besides, I would like to drop layout.css.aspect-ratio-number.enabled in
the next patch because the spec has been updated. It seems we don't have
to keep this pref and we should always use Number.

We still panic in a debug build, so that developers can notice when they
need to add a new static atom after modifying UA sheets.
We also add telemetry to note when this happens, add an app note to a
crash report, in case any crash later on occurs, and re-up the existing,
expired shared memory sheet telemetry probes so we can look at them
again.

We have this optimization where, for non-generic structs, we generate just a
clone / move as the ToComputedValue / ToResolvedValue implementation.
This moves the optimization a bit further down, and refines it so that we still
generate all the relevant where clauses that make it sound, that is, that all
the ToComputedValue implementations of the fields return the same type.
Otherwise this wouldn't be sound and the type would need to become generic.
We add an escape hatch (no_field_bound) for fields that need to be cloned but
which don't implement the trait. This is right now only for the RefPtr<> in the
shared font-family list, and a piece of code in PaintWorklet which looks kinda
fishy, and probably should be fixed (but we don't ship it in Firefox and there's
a pre-existing FIXME for servo, so I punted on it for now).
The other thing this patch does is adding a bunch of ToComputedValue /
ToResolvedValue implementations that are trivial and were missing.

This also fixes some backwards logic in nsBlockFrame::ReflowDirtyLines, and adds
some static assertions to nsGenericHTMLElement that almost cause a very subtle
bug.

* Use debug_unreachable for really unreachable code (having a release
unreachable!() there gives us little to no benefit, as a borked union can
already confuse us into reading an arbitrary pointer as a CalcPercentage).
* Avoid a clone of the calc variant when clamping. We only need to mutate the
clamping mode. This was the only clamp_to_non_negative function that didn't
consume the value.

We never fast-reject numbers (because they could be part of a product). Without
this refactoring we'd accept stuff like calc(10) and crash during the evaluation
for obvious reasons.

This is the meat of the patch. There are a couple improvements done in a couple
later patches which should hopefully be straight-forward.

So as to avoid serializing as identifiers font-families with spaces as part of
the identifier. This avoids serializing confusing escaped sequences if the
beginning of the stuff after the space happens to not be a valid ident start.
This is an slightly more restrictive version of the existing logic, which
happens to also match other browsers in my testing.

We don't actually share _that_ much code across them. This makes callers clearer
and code less confusing, IMHO.
This also has the benefit of not autocompleting path from devtools for
shape-outside.

Tweak the ShapeSourceRepresentation so that it doesn't store Option<>s.
Some renames so that GeometryBox doesn't conflict with the Gecko type, and some
other usual bits / re-exports to deal with cbindgen and generics.
Also, drive-by derive parsing of GeometryBox as it's trivial.
Doing this unfortunately is not possible without removing nsStyleImage first, so
let's do that before.
This makes us serialize in the shortest form for shape-outside, but that's what
we should do anyway.
(aside: the shapes code is a bit too generic, maybe we should unify
ClippingShape and FloatAreaShape...)

We include it everywhere because it's included from gfxTypes.h.
This should avoid including all the generated bindings _everywhere_.

ImageLayer is almost the only usage of Image, so keeping them in the same enum
makes the resulting C++ struct smaller, and makes it map more cleanly to
nsStyleImage.

This simplifies a bit the code, and guarantees that all calc()s have percentages
and lengths.
I also wanted to remove unclamped_length() / specified_percentage() (for the
same reason as the above patch), but they're needed for animations for now. When
I implement min() / max() for <length-percentage> they'll be fixed.

So that it takes one pointer instead of two, and doesn't make nsStylePosition's
size blow up.
This is not as ugly as I was fearing, thankfully, though it requires a bit of
boilerplate. I think it's acceptable.

I'm (sadly) about to make it a bit more complicated to pack it better. So we
may as well do this so it is easier to reason about navigate.
I also reordered things a bit, and removed some From<> implementations and
such.

This is needed to support min() / max() / clamp(), etc, as those need to be a
tree of values and thus need heap storage.
This unfortunately grows LengthPercentage to be two pointers, which is bad as
it blows up the size of nsStylePosition enough to trigger the size assertions.
This patch comments out the assertion for now, the follow-up patches will
uncomment them.

This cleans up and also allows us to keep the distinction between content: none
and content: normal, which allows us to fix the computed style we return from
getComputedStyle().
Do this last bit from the resolved value instead of StyleAdjuster, because
otherwise we need to tweak every initial struct for ::before / ::after.
