[svgwg] Specify that aria states & properties are animatable

AmeliaBR has just created a new issue for 
https://github.com/w3c/svgwg:

== Specify that aria states & properties are animatable ==
See [Editor's Note in the 
SVG-AAM](http://w3c.github.io/aria/svg-aam/svg-aam.html#mapping_animation).

In short:

- If animations can be interactive, then ARIA attributes need to be 
updated to describe the current state (e.g., is something expanded vs 
collapsed, is a play/pause toggle button pressed or not).  
- If animations can run without JavaScript, then the ARIA attributes 
need to be updated without JavaScript.
- Ergo, ARIA attributes need to be animatable. Most of them will 
animate as discrete values, of course, although there are a couple 
that take numerical values.

We don't have full attribute definition boxes for the [ARIA 
attributes](https://svgwg.org/svg2-draft/struct.html#ARIAStateandPropertyAttributes),
 but this could be specified with prose.

If anyone has any objections, please discuss here & now.  Otherwise, 
I'll push changes later this week.
