Add nsOpenGLContextForContext to QCocoaNativeInterface.

Browse Source 
This change enables receiving the native NSOpenGLContext that is used
by a QOpenGLContext. This clearly is non-public api that is only meant to
be used as a last resort for cases where it is really necessary to
get hold of a native context object.
