After changes to an API, we still want to use most of the @remove annotations.

Desired solution

Migrate the @remove annotations through a mapping from old api elements to new api elements. If the mapped apiv2 element is removable, change the target of the annotation.
Otherwise, mark all similar api elements with an unsure (?) @todo annotation.

Create the file package_parser/processing/migration/annotations/_migrate_remove_annotation.py with a function to migrate an annotation with the related mapping.
See #1125.
