[19.0][MIG] base_model_restrict_update: Migration to 19.0

[AungKoKoLin1997]

In Odoo 19, has_group() reads a cached _get_group_ids() (from all_group_ids), so inside a constraint right after changing group_ids it can be stale and return the wrong result. So, I avoided using has_group() in a constraint.

Adding a read-only user to System Administrator from the Group form doesn't trigger the constraint method and the error is not raised at the moment. Same limitation exists in Odoo 19 core. https://github.com/odoo/odoo/issues/228513
