qmlglsrc: fix operation without any qmlglsink
...
E.g. a pipeline like qmlglsrc ! gldownload ! ... would currently fail to
run because the OpenGL context are not created in the correct order.
The QtWindow also needs to know the OpenGL context used by downstream
elements in order to set optimize for the correct GstGLSyncMeta for
synchonisation purposes.

qt: return a different GstGLDisplay object when the first sink requests
...

...
volatile is not sufficient to provide atomic guarantees and real atomics
should be used instead. GCC 11 has started warning about using volatile
with atomic operations.
