style: Remove unused expired boolean in Animation::Transition.

Browse source 
The last caller who used was #14418, which did fix a problem but introduced
multiple. In particular, now transitions don't get expired ever, until they
finish running of course.

That is not ok, given you can have something that the user can trigger to change
the style (hi, :hover, for example), and right now that triggers new
transitions, getting this into a really funny state.

I should give fixing this a shot, but it's non-trivial at all.
