VisibilityCache: Split the visibility checks from the actual caching

VisibilityCache cache does two things: it calculates if something is
visible for the user AND caches the result.

Move the checks to the VisibilityChecker class. Besides better
separation of concerns, this allows us to plug for example an
instrumented checker.
