upgrade-python-groups-id (U1907)

Python code uses groups_id, renamed group_ids in Odoo 19.0.

Applies to Odoo 19.0 and later.

What it does

Reports .groups_id and the string "groups_id" (in values for create and write, domains and mapped), and .users of groups.

Why is this bad?

Odoo 19.0 renamed groups_id to group_ids on users, views, menus and actions, without an alias: the old name raises an error.

Fix safety

Unsafe: groups_id becomes group_ids, which is right for those models but wrong for a custom model that has its own groups_id field.
