I also update the wpt becasue it seems the original one lets <ratio>
support the addition. However, the spec says "Addition of <ratio>s is not
possible".

This is based on the logic in ResponsiveImageSelector::SelectImage (just
simplified because there's no viewport-dependent widths here).

This implements the basic image-set notation without the format()
function (for simplicity).
There's a remaining serialization issue (we should probably skip 1x
resolutions), but that's fine for now, I'll address this in a follow-up
when the feature is testable.
The intention is to do the image selection at computed value time
(keeping a selected index or such), but same, follow-up.
This also fixes an issue where the cors-mode for -moz-image-rect and
cross-fade() was getting ignored when parsing.

This is the first of what will likely be a couple patches for
cross-fade's implementation. Bug 546052 tracks it's complete
implementation.

This does not (yet) upgrade ./rust-toolchain
The warnings:
* dead_code "field is never read"
* redundant_semicolons "unnecessary trailing semicolon"
* non_fmt_panic "panic message is not a string literal, this is no longer accepted in Rust 2021"
* unstable_name_collisions "a method with this name may be added to the standard library in the future"
* legacy_derive_helpers "derive helper attribute is used before it is introduced" https://github.com/rust-lang/rust/issues/79202
This conversion can lead to floating point errors and extra work when
computing animations. Avoiding it allows animation-iteration-count-009.html
to pass.
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 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.

Rename fill_idx to fill_start, to indicate it is not a single value but a
range. Also change a numeric_limits<>::max() involving the fill_start to use
decltype() to ensure its type matches that of the auto-generated structure's
field, while we're touching that code.
The test to ensure only a single repeat value is allowed will be removed by a
later commit.

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.

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...)
