QFont: Prefer setFamilies() over setFamily()

By depending on setFamilies() then we can be sure that font names with
spaces, commas, quotes and so on are correctly handled without being
misinterpreted. For now it will split on the comma when a string
containing one is passed to setFamily. But from Qt 6.2 this will be
removed to preserve the family string as a convenience function.

[ChangeLog][QtGui][QFont] Indicated that setFamilies/families is
preferred over setFamily/family to ensure that font family names are
preserved when spaces, commas and so on are used in the name.
