When running `getDisplayMedia` from an `iframe` and then destroying that
`iframe`, the destrutcor for ScreenCaptureKitDeviceMac gets run, but it
doesn't clean up the observers for the shared macOS picker.
In this change we remove the observer on cleanup and fix the associated
crash:
*** Terminating app due to uncaught exception 'NSGenericException', reason: '*** Collection <__NSArrayM: 0x12c024123a0> was mutated while being enumerated.'
