Remove core's parameter typehints of CacheableMetadata within interfaces and base classes

I think between changing the type hints to the interface and using class_alias() that would allow us to do the other issue without breaking bc, so still seems valid.

   I doubt anyone is subclassing this, but I think we should probably remove the entire parameter from the interface in Drupal 10, add a commented out one to indicate it's going to be added back with the new type hint, then change the type hint in Drupal 12. Pretty sure this allows an implementation to update their own type hint in Drupal 10, see example 3 on 🌱 [Meta] Implement strict typing in existing code Active .

   And the same here.
