Emilio Cobos Álvarez 6c32b964cd Bug 1807003 - Centralize animation data in slots. r=smaug,firefox-animation-reviewers,boris
This should both be faster and simpler. Also will allow us in the future
to animate more pseudos without having to add a gazillion properties.

I think we should try to clear more stuff (maybe the whole animation
data) on unbind, but that's a bit tangential.
