[MIG] mail_compose_select_lang: Migrated to 10.0

Note this migration comes with a feature loss as translated reports
is no longer possible via a python override (translations are done
in the report templates themselves; therefore every report would
need an inherited version).

This module was migrated from 8.0 to 10.0 directly, which explains
the consequent diff.

+Known issues / Roadmap
+======================
+
+* Translating attachments is no longer supported as the mechanism for report
+  translation has changed. Every report template is translated by a rebrowse
+  in the template itself; to make them translatable an inherited view is needed
+  for *every* report.
