[csswg-drafts] [mediaqueries] media feature for reduced frame rate (due to low energy/battery saver mode) (#12654)

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

== [mediaqueries] media feature for reduced frame rate (due to low energy/battery saver mode) ==
Often when devices enter “battery saver” or low power mode, they will reduce the frame rate of animations (might be tied to reduced refresh rate? idk). This can make an animation so choppy that they might not be worth having, especially when there is motion. I’d love to have a way of querying this.

The `update` media feature exists with the keywords `none`, `slow`, and `fast`, but `slow` is _very_ slow, so `fast` will almost always be triggered. Feels not totally related to what I want. We almost need an in-between keyword or maybe an entirely different media feature. It might even be nice to query a range (i.e. if the device can do more than <var>x</var> frames per second, then show the animation).
