Servo is going to maintain a fork of `malloc_size_of` internally so that
Stylo does not need to have an implicit dependency on all of the crates
that need an implementation of `MallocSizeOf`. In order to prepare for
this, implementations that are only used in Servo should be removed
(unless they are used in Stylo itself). In addition, we can remove some
Gecko-specific implementations as well in order to make downstream Stylo
a bit cleaner.

An unknown implicit scope implies matching to document root now.
... This also re-tightens the removed assert in bug 1931054, as implicit
scope root will be always assigned something.

This improves the behavior significantly. Transitions that are not
running on the compositor but are throttled on the main thread due to
being scrolled out of view have the same issue as compositor animations.

Make it an alias of the preserve-spaces value, and don't bother
serializing the shorthand to that value.
Update internal usages to the standard keyword.

We want to conditionally parse `anchor()`, but:
1. It's not really a unit.
2. When interleaving gets implemented, we'd treat it just line `<length-percentage>`,
but still need the conditional parsing.
Differential Revision: https://phabricator.services.mozilla.com/D228551
32-bit build does this, and causes a circular dependency when `anchor()` is
added. Since its fallback is `<length-percentage>`, there'd be a circular
dependency.

Bug 1926969 introduces a new example of computational dependence:
Color-scheme dependent colors like `light-dark()` and system colors. So
specific references to lengths, like `allows_font_relative_lengths`,
should be generalized.
This patch also renames `ParsingMode::DISALLOW_FONT_RELATIVE` to
`ParsingMode::DISALLOW_COMPUTATIONALLY_DEPENDENT`.
ParserContext::allows_computational_dependence is added for convenience.

When I rewrote this code in bug 1874050, the assumption was that doing
the right thing was fine because we were more likely to take the fast
path for the owned properties (the parent_ptr_eq()).
But given this shows up in profiles, let's do the order-aware comparison
(which might return false in some cases where it doesn't need to, but
seems to be a better trade-off with tons of custom properties).

Product nodes are eagerly resolved during parse time, but sum nodes are
not. This might cause floating point inprecision in sum nodes, which
leads to invalid calculations, e.g. `round(down, (7 - 1) / 3, 1)` would
end up being `round(down, (2.3333333 - 0.33333334), 1)`, then
`round(down, 1.99999996, 1)`, which equals `1`, which is incorrect.

We now fully support the full ColorFunction in the ComputedStyle struct
in layout. This solves an issue where colors are copied on the C++
side.
Some structs had to be renamed to avoid name collisions in the generates
C++ code.
Some specified structs has the #[repr(C)] attribute now to include them
in the ComputedStyle struct. This is not really correct as they are
specified values and only computed values should be there. Splitting all
the unit structs into specified and computed is a lot of changes so
there is a follow up bug here:

When an alpha component is omitted, instead of defaulting to opaque,
colors with an origin color used the alpha from there.

When we have a color that can't be resolved at parse time (or should not
be resolved) then we store the data that was parsed as is to preserve
all the data for round tripping.

Color components can now preserve parsed data, including calc nodes, if
required.
Some of the computed color tests fail, because we don't have the origin
color readily available to determine which color format to use. (e.g.
color instead of rgb). Fixes are in a follow up patch: D220268

The zoom factor is stored as a fixed point number, and the effective zoom may
be close to 0 (because we have to mulitply the zoom values of ancestors).
So we have to make sure we don't divide by zero because the effective zoom
could be zero.
