Implement animation for color-filter
https://bugs.webkit.org/show_bug.cgi?id=185092
rdar://problem/39773810

Reviewed by Tim Horton.

Source/WebCore:

Implement animation of color-filter.

This requires tracking whether the color-filter function lists match for both old and new
animation code paths.

The filter-related ProperyWappers in CSSPropertyAnimation are cleaned up to use a single wrapper,
which has to pass the propertyID to the blend function so we know which "lists match" to check.
This wrapper reports that its accelerated for filter and backdrop-filter, but not color-filter.
