macOS: Clear NSOpenGLContext drawable when QNSView is about to go away
Calling doneCurrent() on a QCocoaGLContext only clears the current
context, but doesns't reset the drawable (view) of the context. In
most cases this is fine, but it has been observed to cause issues
when using the software GL renderer on Big Sur and above.
To be a good citizen we clear the drawable of any of our contexts
that are tied to the NSView this about to be go away.
Pick-to: 6.2 6.2.2
