…utation

If one change the use_create_lots field on stock.picking.type, we should not trigger
all move lines recomputation of that picking type.

This change allows to take advantage of field descriptors on relational fields to initialize the comodel_name from optional type's arg that can be specified on field declaration. With this change, this kind of syntax becomes valid and will avoid errors in the comodel_name args.

partner = fields.Many2one[Partner]()

This code is not part of the _Relational class constructor since we need to get access to the __orig_class__ attribute which is set on the instance by the Generic metaclass after the call to the _Relational class constructor.

To avoid circular import it's common to reference a type as a string for generics:

```python
from odoo import models, fields

from typing import TYPE_CHECKING

if TYPE_CHECKING:
    from .res_partner import Partner as ResPartner

class Thing(models.Model):

    _name = "thing"
    _description = "Thing"

    partner_id = fields.Many2one["ResPartner"]()

```

In such a case, the type's arg at runtime is not a class but an instance of typing.ForwadRef. In such a case, the comodel_name is computed by converting the classname provided by te ForwardRef from CamelCase to dot.case

the typing_extension is required by the type annotations

Calls a dedicated method to clone an existing field to ensure that the type args is preserved when instantiating the cloned instance

As find_module has been deprecated since python 3.4:

https://github.com/python/cpython/blob/05c28b08f6e2fc8782472b026c98a3fdd61a2ba9/Lib/importlib/_bootstrap.py#L1347

and warnings added in python 3.10:

https://github.com/python/cpython/blob/f91dfdf5ff9f68a4b012e1b70ab9997c6dc1542d/Lib/importlib/_bootstrap.py#L764

to respect the PEP-451 specification : https://peps.python.org/pep-0451/

So, override the find_spec() method to display depreaction warnings if applicable.

Allow building a wheel or an sdist through the pep517
interface, taking care of the required pre-processing
to copy addons in odoo/addons.

Force the setuptools compat mode for editable installs.
This mode is the simplest, since it just installs a .pth
files which extends PYTHONPATH with the Odoo root directory.

This allows launching Odoo with "python -m odoo".

This manner of launching python applications is now widespread.
In particular it makes it easier to configure an IDE debugger to run with the correct python version.
