PURPOSE
Mass mailing is currently a bit messy. As SMS will be added as a way to notify
people in mass through SMS let us take this opportunity to somehow clean this
application: organization, light code cleaning, model renaming.
SPECIFICATIONS
Rename mail.mass_mailing model to mailing.mailing. Rationale :
* mailing is now a prefix for mass mailing models;
* mailing.mailing is easier to read / find / understand;
Note that mail.mass_mailing.campaign is not updated as it is likely to be
removed soon and replaced by simple utm.campaign model.
MIGRATION
mail.mass_mailing model -> mailing.mailing
mail_mass_mailing table -> mailing_mailing

PR #34938
Issue: wysiwyg asset slow down the loading of the website, error
inadvertently introduced: https://github.com/odoo/odoo/pull/29775
The assets are now loaded assynchroneously, when the editor is needed,
its assets will be loaded.
closesodoo/odoo#30700
The refactoring also had to be done in order to create a set of unit
tests.
Each behavior can be tested, including the behaviors performed as a
consequence of keyboard interactions (for instance: Enter, Tab...).
This commit also contains some changes to test_utils that were
necessary given the new structure of the wysiwyg editor.
