[FIX] mail: fix tracked field with groups

Bug
===
Since 0bd14547a7f6389192f522da08527a2c8a13f1a8,
When editing a record which has a tracked field with a group, and if
the current user is not in the group, an error is raised.

Technical
=========
When we get the tracked fields, we must care about the group of the
current user and keep only the tracked fields the user have access to.

To do that, we use `fields_get`, which will return only fields accessible
by the current user group.

The method `_get_tracked_fields` is cached, but it need to depend on
the current user (and also if we are in sudo mode or not), because the
function will return different results, depending on the group of the
user.

Task-2250070

closes odoo/odoo#51915
