Bug 1245748 - Update handling of 'composite' dictionary members to match changes to the spec; r=heycam, r=bz

Specifically, for the 'composite' member on keyframes, we now indicate "use the
composite value specified on the effect" using a missing/undefined 'composite'
member as opposed to a null value.
