Standardize the mechanisms for copy annotations to component/implementation class

[realityforge]

A few attempts have been made to build on Arez functionality in other downstream projects. One challenge is how to copy annotations to generated subclasses to trigger other annotation processors. See arez/arez-persist#4 for a description of such an issue.

It would be useful to define a mechanism by which Arez derived frameworks could cooperate and allow mixing frameworks. An annotation on an annotation style approach should do the trick. This would make all sidecar solutions a lot easier to implement.
