Add QUOTIENT_API throughout non-generated code

This include all (hopefully) classes/structures and functions that have
non-inline definitions, as well as namespaces with Q_NAMESPACE since
those have non-inline (as of Qt 5.15) QMetaObject - for that a new
macro, QUO_NAMESPACE, has been devised to accommodate the lack of
Q_NAMESPACE_EXPORT in Qt before 5.14.
