Enable floor plan for all PoS Restaurant config. To accomplish this, we are
removing the following fields:
- `pos.config.is_table_management`
- `res.config.settings.pos_is_table_management`.
All access to `is_table_management` can be replaced by `module_pos_restaurant`
because originally, `is_table_management` can only be true if
`module_pos_restaurant` is true.
To adapt the tests, we should manually set `module_pos_restaurant` to `False` for
the `pos.config` used in tests outside `pos_restaurant` addon. This is because
when pos_restaurant addon is installed, it sets every new `pos.config` record to
be restaurant by default.
