SGSR: name the sharpness slider after the upscaler it is driving

The slider is shared, and that is deliberate -- the two upscalers want the
same thing from the user and a second control would only let them disagree.
But the NUMBER means different things to each: RCAS stops for FSR1, a 0..2
edge-sharpness factor for SGSR. Labelling it "FSR Sharpness" while SGSR is
selected says the setting belongs to something that is not running.

It now names whichever is selected, in both pickers.
