As part of moving towards more shared data structures for animation, this patch
makes ElementPropertyTransition inherit from ElementAnimation. At the same time
we switch from storing the target property, start/end values, start time, delay,
and timing function on the transition to the corresponding location in
ElementAnimation.
Since nsDisplayList::AddAnimationsAndTransitionsToLayer was already doing this
conversion in order to create animations to pass to the compositor thread, we
can remove the conversion code from there and just use the ElementAnimation data
structures as-is.
A number of assertions are added to verify that transitions are set up as
expected (namely, they have only a single property-animation with a single
segment). As we move to more generic handling of animations and transitions
these assertions should disappear.
