Support threaded rendering for Nvidia EGLStreams
Create and update the texture on the GUI thread. Make sure there
is a valid context on the GUI thread: create one if necessary, and
share it with the global share context.
Note: this requires that threaded compositors set the
Qt::AA_ShareOpenGLContexts application attribute.
Task-number: QTBUG-63039
