shiboken6: Skip Q_ENUM helper functions when PySide extensions are enabled

The helper functions qt_getEnumMetaObject() and qt_getEnumName()
defined by Q_ENUM had to be rejected in the typesystem files in each
namespace.  Pass the ApiExtractor flags to the meta builder to cleanly
detect all Qt special functions and automatically reject them when
PySide extensions are enabled.

[ChangeLog][shiboken6] The Q_ENUM helper functions
qt_getEnumMetaObject() and qt_getEnumName() are now automatically
rejected when PySide extensions are enabled.
