[IMP] mail, test_mail, *: add new email.cc.mixin on main models

*: crm, project, maintenance, hr_recruitment

When a record is created from an email, cc can be lost. This commit
proposes a new mixin to keep cc on the record and allows to create
partner for each of them when sending a message from the chatter.

The mixin is added on the mail recors that can be created from mail.alias:

document
helpdesk.ticket
mrp.eco
quality.alert
hr.applicant
crm.lead
project.task
mail.channel
maintenance.equipment
