[REF] mass_mailing: move from onchange / default to stored editable computed fields

PURPOSE

Try to move from onchange / default_get to stored editable computed fields.
Normally behavior should be the same (computed or set by user), with support
in create / write + onchange without additional code.

SPECIFICATIONS

Update classic fields with onchange to stored editable computed fields. It
means their value will come either from manual user input, either computed
based on triggers. Purpose is to remove all onchange and default_get when
possible.

Clean fields definition inconsistencies, like default / required on computed
fields. Indeed computed fields should always have a value, maybe coming from
user input. They should not have default / required that are attributes for
classic fields.
