Bug 2006839 [wpt PR 56850] - Support calc values in random() fixed, a=testonly

Automatic update from web-platform-tests
Support calc values in random() fixed

Fixed values in <random-value-sharing> parameter of random() function
should accept not only numeric literals but also calc expressions.
Now instead of having double fixed random sharing value, we store
CSSPrimitiveValue instead.
