Support androidx.appcompat.widget.TooltipPopup as window type

[pyricau]

See #30 (comment) for details

View.windowType should return TOOLTIP if the window was created by androidx.appcompat.widget.TooltipPopup

We need to do this without having a direct bytecode reference to androidx.appcompat.widget.TooltipPopup or adding a transitive dependency, as curtains needs to remain android x free.

Actually we can't list all WindowType., because developer can use WindowManager to create window freely.

I am thinking about the real usage of WindowType. Why do we need it ?
