DRS improvements

[rfomin]

• Added 30-frame history and 15-frame cooldown period after resolution change.

• Simplified and tweaked downscale/upscale threshold parameters.

Is this frames or tics?

What about the idea to uncouple the target framerate from the screen's native framerate, because the latter might be inreasonably high? That is, don't change the resolution of the frame rate drops below e.g. 240 Hz, but only if it drops below e.g. 60 Hz.

It's frames.

User can already set frame limiter to 60 and it will be target refresh for DRS. I'm not sure if we should force it. Usually PC with high refresh monitor also have fast CPU.

Fair enough. Should we rename it "target frame rate" in the menu then?

In SDL3 we can request a list of all available refresh rates. Maybe we should make a termo or some other UI element here, not sure yet.

We could still rename the parameter now, though.
