-----------
Serialize hsl()/hwb() with at least one `none` component value as hsl()/hwb()
https://bugs.webkit.org/show_bug.cgi?id=317102
Reviewed by Darin Adler.
CSS Color 4 was changed so that now when there is at least one `none` component
in an hsl() or hwb() color function, we preserve the spelling of the hsl()/hwb()
functions, rather than converting to rgb().
See https://drafts.csswg.org/css-color-4/#css-serialization-of-srgb.
Updates WPT tests to test new serialization.

* Source/WebCore/platform/graphics/ColorSerialization.cpp:
- Remove specialized functions for lab-like and lch-like function
serialization, creating a shared
`serializationUsingNamedFunction` that can be used by HSL and HWB as
well. It uses a new helper,
`normalizedNumericComponent` to figure out if hue normalization is needed
using the ColorModel's
componentInfo table.
* Source/WebCore/platform/graphics/ColorSpace.h:
- Added a function to get the ColorSpace from a color allowing generic
contexts without a
template argument specified type to easily access the ColorSpace.
