QStandardPaths: add GenericConfigLocation

This is what ConfigLocation was meant to be. A directory shared by all
applications. Unfortunately when I wrote the fallback on Windows,
I picked DataLocation (which is app-specific) instead of
GenericDataLocation (which is shared between apps). This makes it
impossible to have config files shared between apps, e.g. for libraries.
It also makes ConfigLocation quite inconsistent (on Windows one cannot
use it to load another app's config file, while it works everywhere else).

All this is fixed by GenericConfigLocation, which is shared between apps.
