Issue type for Screen.grabWindow

PySide2 function: Screen.grabWindow(WId) requires an WId and refuse int.

But WId type is not accessible from PySide2. Furthermore Widget.winId() function returns an int and not a WId. So it is impossible to grab any window from grabWindow.

Simplest source code to reproduce:

-------------------------

from PySide2.QtWidgets import QWidget, QApplication
from PySide2.support.signature import mapping

app = QApplication([])
widget = QWidget()
app.setActiveWindow(widget)
widget.show()

window = QApplication.activeWindow()
screen = QApplication.primaryScreen()
wid = window.winId()
w = screen.grabWindow(wid)
