Sharpening in the in-game menu, named for the upscaler in use

The slider was missing from the in-game menu entirely -- it only existed in
the settings screen. That is the wrong way round: the quick menu is where the
upscaler gets changed mid-game, and having to leave the game to tune what you
just switched to defeats the point of it being there.

Shown only for FSR and SGSR, since nearest and bilinear have nothing to
sharpen.

The label follows the selection in both places, because the number does not
mean the same thing to each: it is an RCAS stop to FSR and an edge factor to
SGSR, and a slider named for the upscaler that is not running is simply
wrong. One control rather than two, deliberately -- both upscalers want the
same thing from the user, and a second slider only lets them disagree.
