Add "ProMotion" to feature support matrix

[Donkey-Doug]

I think it is a good idea to also add promotion in the feature support table. Currently we only have "main display" and "brightness". However, users might think support for the main display also means support for promotion

If desired it can be called 120Hz VRR (variable refresh rate) such that we do not use Apple's marketing names.

(hint for anyone else having trouble parsing, Promotion = ProMotion)

I'd really like for this to be added since 120hz VRR support is the main thing holding me back from using Asahi Linux as my main OS (aside from sleep battery drainage) and being able to quickly check it in the feature support matrix would be helpful.

I'm in the same boat especially since there's now OpenGL 4.6 compliance, but I can't go on without my buttery smooth cursor haha, but asahi is healthily feeling better and better.

This is also one of the main features holding me back from trying to use Asahi.

Once you get used to a buttery smooth 120hz display, you really can't go back to 60hz.

For me it's not necessarily "ProMotion" or variable refresh rate, BTW, but simply 120 Hz, whether or not it's adaptive.

Gentle bump, it's been two years, this is a deal breaker for me.

Bump again, I've checking every few months in hopes of this feature being implemented. You guys do amazing work and this project has come so far, but without high refresh rate support, a lot of enthusiasts can't make the switch from MacOS.
