Calling swapBuffers with the surfaceHandle of 0 returned by QWindow

This is simpler than the existing texture cache in QtOpenGL, as it only
serves the GL paint engine. There's one per context group, to simplify
the design and to prevent performance degradations.

can now add a test case for what happens when a shared resource is still
valid while the last context is destroyed.

Since QOpenGLContext is now a QObject, it needs to be moved to, or
created in, the thread where it's going to be used.
