Windows: When using "Create shortcut", use the game's icon instead of PPSSPP's.

Browse Source 
Since on Windows, shortcuts can't embed icons, we first save the game's
icon .png as an .ico in the SAVESTATE folder (there might be a better
place, but it also doesn't seem worth it to create a new folder for
this).

Part of #10885 (Android functionality still missing, for example).
