CSS Gradients: interpolation mode should default to OKLab if any non-legacy color syntax colors are used in the stops
​https://bugs.webkit.org/show_bug.cgi?id=235071

Reviewed by Darin Adler.

LayoutTests/imported/w3c:

Update test to also include non-legacy color syntax stops and update results
to match new expected behavior.

Source/WebCore:

Change the default interpolation mode for CSS gradients that have any color stops specified using non-legacy
color syntax (e.g. color(...), lab(...), oklch(...), etc.) to OKLab from sRGB.

This is the current behavior specified (kind of, it could be clearer) by the spec, but I have concerns about
whether it is a good idea for the behavior to be dependent on what syntax style you use. This has been raised
with the editors at ​https://github.com/w3c/csswg-drafts/issues/6914.

To implement, we now compute the default color interpolation method from the parsed stop list and pass the
result to CSSGradientValue along with the stops and other data. The CSSGradientValue needs this information
avoid computing on serialization, since we need to conditionally exclude either "in srgb" or "in oklab"
depending on which one is computed.

To continue passing the interpolation color method to the CSSGradientValue constructor so it can be immutable,
we now need to consume all the color stops before we can create the CSSGradientValue. This also allows us to
pass the stops to the constructor and make them immutable as well.

     3        CSS Gradients: interpolation mode should default to OKLab if any non-legacy color syntax colors are used in the stops
     4        https://bugs.webkit.org/show_bug.cgi?id=235071
     5
     6        Reviewed by Darin Adler.
     7
     8        Change the default interpolation mode for CSS gradients that have any color stops specified using non-legacy
     9        color syntax (e.g. color(...), lab(...), oklch(...), etc.) to OKLab from sRGB.
     10
     11        This is the current behavior specified (kind of, it could be clearer) by the spec, but I have concerns about
     12        whether it is a good idea for the behavior to be dependent on what syntax style you use. This has been raised
     13        with the editors at https://github.com/w3c/csswg-drafts/issues/6914.
     14
     15        To implement, we now compute the default color interpolation method from the parsed stop list and pass the
     16        result to CSSGradientValue along with the stops and other data. The CSSGradientValue needs this information
     17        avoid computing on serialization, since we need to conditionally exclude either "in srgb" or "in oklab"
     18        depending on which one is computed.
     19
     20        To continue passing the interpolation color method to the CSSGradientValue constructor so it can be immutable,
     21        we now need to consume all the color stops before we can create the CSSGradientValue. This also allows us to
     22        pass the stops to the constructor and make them immutable as well.
     23
