Switch the remaining classes in core/css to use downcast helpers (10/10)

The following class is migrated: CSSValueList. It is the last user of
DEFINE_CSS_VALUE_TYPE_CASTS, and so the CL also removes the macro
definition altogether, and core/css is free from using it.

Note that in cases where the premise for the downcast was being checked
with CSSValue::IsBaseValueList instead of CSSValue::IsValueList,
the use of DynamicTo<CSSValueList> did not happen, so the CL preserves
its existing logic 100%.
