interface RefinableCacheableDependencyInterface in Drupal 9

Allows to add cacheability metadata to an object for the current runtime.

This must be used when changing an object in a way that affects its cacheability. For example, when changing the active translation of an entity based on the current content language then a cache context for that must be added.
