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'll use `CalcNode` as the specified value representation for <length> and
<length-percentage> values, so they'll have to implement ToCss.
There's one minor issue (two calls to to_css() instead of to_css_impl() which
are addressed later in the series).

I suggested the compat_mode bit in D62923 but it was somehow only applied to one
of the branches.
Also rustfmt the code for consistency, and add a local alias.

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.

For now, we still bail out at the stage of getting the calc node into a
CalcLengthPercentage if we couldn't simplify the min() / max() / clamps()
involved.
After this plan is to use just CalcNode everywhere instead of
specified::CalcLengthPercentage, and then modify the computed
CalcLengthPercentage, which would look slightly different as we know all the sum
terms for those are a struct like { Length, Percentage, bool has_percentage } or
such, so all the simplification code for that becomes much simpler, ideally.
Or we could turn CalcNode generic otherwise, if it's too much code... We'll see.

Keep a flat list of sum members. Simpify product and division ASAP.
I want to preserve the tree for a bit longer to implement min / max / clamp.
This doesn't do anything for it that we weren't doing already, but it helps to
eventually keep this specified representation and the equivalent computed
representation for <length-percentage> values.
Enable the tests for the comparison functions too, to prevent regressions.

Per SVG2 spec, the EBNF allows the path data string to be empty.
An empty path data string disables rendering of the path.
Therefore, we should make path('') a valid path string.
The related spec issue: https://github.com/w3c/fxtf-drafts/issues/392.
Now we serialize `path("")` as `path("")` for offset-path and clip-path.

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.
Differential Revision: https://phabricator.services.mozilla.com/D60194
This is just not a thing you can do if you have min() / max() / etc, as the min
/ max value may depend on the percentage basis.
