give a option to place Popup on parent item

https://doc.qt.io/qt-6/qml-qtquick-controls-popup.html#popupType-prop

suggesting adding a new "Parent" popupType. when the specific popup is "Parent" type,

it will place Popup on its parent instead of the overlay layer.

it is useful when you have a Drawer with a transparent header or footer above it.

I know we have https://doc.qt.io/qt-6/qml-qtquick-controls-popup.html#showing-non-child-items-in-front-of-popup

but it is hard to position for the header and footer case.
