Add FractionalLayoutUnit version of blend to AnimationUtilities
​https://bugs.webkit.org/show_bug.cgi?id=81572

Reviewed by Eric Seidel.

Add version of blend method that operates on FractionalLayoutUnits. This
will be used in place of the integer version in many places once we
enable support for subpixel layout.

No new tests.

Include math.h to make GTK build happy.
