[MIG] base_view_inheritance_extension: Migration to 15.0

* Removed `list_add` and `list_remove`, they've been deprecated and
implemented in Odoo core since several versions ago.

* Removed `move`, as it has also already been implemented in core several
versions ago.

* Replaced `python_dict` by `update`, that performs an operation similar
to :meth:`dict.update`, but on the ast.Dict.
