[AVFoundation] Improve the callback in AVAssetImageGenerator.GenerateCGImagesAsynchronously.

[rolfbjarne]

Add an overload to AVAssetImageGenerator.GenerateCGImagesAsynchronously that
takes a callback we call with a managed CGImage instance instead of a CGImage handle.

This makes the API a bit easier to use.
