Matthew Waters 18972fc942 add new plugin for Qt 6 rendering inside a QML scene
- Based heavily on the existing Qt5 integration however:
  - The sharing of OpenGL resources is slightly different
  - The integration with the scengraph is a bit different
- Wayland, XCB and KMS have been smoke tested.  Android, MacOS/iOS,
  Windows may or may not work.
