[fxtf-drafts] [filter-effects-2] Define `backdrop-filter` with animation type (#496)

cdoublev has just created a new issue for https://github.com/w3c/fxtf-drafts:

== [filter-effects-2] Define `backdrop-filter` with animation type ==
[`backdrop-filter`](https://drafts.fxtf.org/filter-effects-2/#propdef-backdrop-filter) is defined with `Animatable: yes`, but [Web Animations 1](https://drafts.csswg.org/web-animations-1/#animating-properties) requires `Animation Type`:

> How property values combine is defined by the ***Animation type*** line in each property’s property definition table

`w3c/reffy` (spec crawler) does not normalize `Animatable` to `Animation Type` therefore users have to check both `propDef.animationType` and `propDef.animatable`, which is not great.

Ideally, I think its value should also conform to the values listed in Web Animations instead of `yes`, eg. *"See prose in [Animation of Filters](https://drafts.fxtf.org/filter-effects-1/#animation-of-filters)"*, like [`filter`](https://drafts.fxtf.org/filter-effects-1/#propdef-filter).
