-----------
Implement calc-mix()
https://bugs.webkit.org/show_bug.cgi?id=313461
Reviewed by Darin Adler.
Adds support for the calc-mix() function from CSS Values 5
(https://drafts.csswg.org/css-values-5/#calc-mix) which implements a
weighted average of a list of terms.
The current spec is a little unclear on simplification with the open
questions being tracked in https://github.com/w3c/csswg-drafts/issues/13839.
The implementation is enabled behind a new CSSCalcMixEnabled settings value.
