Windows: Freetype: Load fonts from the user locations

Since Windows 10 update 1809 it is possible to install fonts as a user
so they are only available for use by the user and not on the system.
So this location in the registry needs to be checked as well when
looking for available fonts.

Fixes: QTBUG-73241
