Add support for using 'currentcolor' with color-mix()
https://bugs.webkit.org/show_bug.cgi?id=250459
Reviewed by Darin Adler.
To support 'currentcolor' as the origin color in a color-mix()
value, this change adds a new CSSPrimitiveValue type called
CSSUnresolvedColor as a peer to the existing color value, that
represents, as the name suggests, unresolved color values.
In this change, CSSUnresolvedColor is only used for color-mix(),
but it is implemented in a way so that we can add support for
other unresolved colors like relative colors.
In addition to CSSUnresolvedColor, to fully support 'currentcolor'
StyleColor was updated to add a third kind in addition to Color
and CurrentColor, for color-mix(). This allows for us to do late
evaluation of the color-mix() in the case of a 'currentcolor'
(or even in more interesting cases like an origin which is another
color-mix that itself has 'currentcolor' as the origin).
CSSUnresolvedColor also fixes an issue where we were not preserving
calc() values for the percentages in color-mix() in the specified
value serialization.

CSSResolvedColorMix serves as the implementation of the final
resolved color-mix(), and is used for eager mixing (in the case
of the Raw variant currently used on workers) and in StyleColor
when doing the final resolution.

CSSUnresolvedColor serves a container for unresolved colors
in CSSPrimitiveValue. For now it only supports color-mix(),
but is setup to support other kinds going future.

Value type for unresolved color-mix(), used as the "specified
value" for color-mix() to correctly serialize per-spec and
correctly resolve to a structured StyleColor at style building
time.

Renames color parsing functions to use the Raw suffix to match convention and

in that it is not eagerly resolving.
