Copy calls 'create' on 'self' which means self is not a void recordset. In
mail this causes issues as it may have an impact of values generated for
aliases, which depends on 'self' when calling '_alias_get_creation_values'.

Cleanup alias usage and definition. Prepare code to ease future changes and
improvements. Notably
* add a 'alias_email' computed field on the mixin allowing to have the
complete alias email when set, and False in case it is inactive or linked
to an inactive alias domain;
* remove unnecessary alias_id field definition when just the help differs
from the standard definition coming from the 'mail.alias.mixin';
* use fields coming from 'inherits' instead of using alias_id and its sub-
fields; notably use 'alias_display_name' and 'alias_email' fields;
* remove useless custom code and management;
* improve alias parameters support code in configuration parameters;

Some models would like to use the 'mail.alias.mixin' but it creates an alias
for each record in the parent model. This leads to a lot of unused aliases
if only a subset of those records really use aliases i.e. a lot of aliases
with 'alias_name' being 'False'.
In this commit we introduce a new mixin 'mail.alias.mixin.optional' that
behaves like the old 'mail.alias.mixin' but without having the 'alias_id'
field required i.e. without the "inherits". When creating a record without
giving an 'alias_name' no alias is created.
In future commit, we plan to use it notably to remove custom code in account
journal model and make it more standard. Using it in more models will be done
later, but it is a candidate to cleanup unused aliases related to discuss
channel model.
