Artem Pianykh	237aac4cd0	[nullsafe] Introduce @Nullsafe annotation ... Summary: - Add `Nullsafe` annotation as a general mechanism to specify type-checking behaviour for nullsafe. - Document annotation params and provide usage examples with explanations. - Add tests to demonstrate the behaviour with different type-checking modes. No implementation is added. This diff serves as an RFC to hash out the details before I dive into code.
