Implement the QEnum/QFlag decorator, V2

This implementation allows module-level and scoped QEnums
which are Python enum types. Scoped types are registered in Qt's meta
object system.

Usage of QEnum/QFlag with decorator or function call:

    from enum import Enum, Flag, auto

    from PySide2.QtCore import QEnum, QFlag, QObject

    class Compass(QObject):

        @QEnum
        class Orientation(Enum):
            North, East, South, West = range(4)

        class Color(Flag):
            RED = auto()
            BLUE = auto()
            GREEN = auto()
            WHITE = RED | BLUE | GREEN

        QFlag(Color)
