Simon Charette ed7898e1b5 Fixed #28862 -- Disabled optimization of AlterFooTogether and RemoveField.
AlterFooTogether operations cannot be swapped with RemoveField operations on
the same model as they could be removing the the same field as well.

Since AlterFooTogether operations don't track what their previous value was,
it's impossible to determine whether or not the optimization is safe so the
only way to proceed is to disable the optimization.

Thanks Ramiro Morales for the in-depth analysis of the issue.

Simon Charette 8a03445885 Removed in_between from Operation.reduce()'s signature.
It isn't used since FieldOperation.references_model() takes into
account models referenced by the field it's operating on.

perform the required repointing.

Simon Charette 2faeb21d2f Moved _get_model_tuple() to the base Operation class.
This allows field and special operations to use this logic.

Amos Onn bd3c2900fc Fixed #25892 -- Optimized SeparateDatabaseAndState.database_backwards().
Now intermediate states in the database_backwards are cached, similar to
the executor's migrate() (or _migrate_all_backwards()). This makes the
migration run much faster (O(n) instead of O(n^2) over number of
database_operations).
