[scroll-animations] update `ComputedEffectTiming` to use `CSSNumberish`
https://bugs.webkit.org/show_bug.cgi?id=279727
rdar://136031059
Reviewed by Chris Dumez and Tim Nguyen.
To accommodate progress-based timelines (such as `ScrollTimeline` and
`ViewTimeline`),
the following properties of `ComputedEffectTiming` have been updated to be
`CSSNumberish`
(aka `double or CSSNumericValue`) to return `%` values: `localTime`, `endTime`
and
`activeDuration`.
Before we do the work to actually compute such values, we update the IDL files
for these
properties and back them with a new type called `CSSNumberishTime` which can
automatically
convert from and to `CSSNumberish`. The benefit of `CSSNumberishTime` are
twofold.
First, it removes the need to deal with `std::variant` switches and then the
various units
which `CSSNumericValue` can represent with either "time" or "percentage"
semantics and methods
to access such values.
Second, it supports various math operators to directly add, subtract and
compare the time
or percentage values held by `CSSNumberishTime`. This will be critical when we
adopt `CSSNumberish`
through more of the Web Animations API, especially with the `Animation` APIs
which are used
throughout the Web Animations codebase currently as `Seconds`. This should make
the move to
`CSSNumberishTime` mostly transparent for most of our code.

that the Web Animations code automatically
gets access to `CSSNumberishTime.h` via this oft-included file.
