Share blend progress code
https://bugs.webkit.org/show_bug.cgi?id=74464
Reviewed by Dean Jackson.
Lots of places in the code had copies of the animation interpolation
logic "from + (to - from) * progress", in various forms.
Coalesce all these into calls to a few new inline functions in a new
AnimationUtilities.h header. Color and Length get their own blend fuctions
in their respective headers.
Covered by existing tests.
