QWindowsFontDatabase: replace a QPair with a dedicated struct

Pairs are easy to use, but they have no semantics attached: Two
QPair<QString, QString> compare equal, e.g., even though one is used
as a FontAndStyle and the other as, say, a type/subtype. It also
carries no information for the reader of the code.

So, write a minimal struct with equality and qHash() instead.
