[evolution-data-server/tintou/camel-error-domains] M!61 - Camel: Add several headers to provide GType for error domains

[Corentin Noël <corentinnoel src gnome org>]

commit 8603bc01db87a257f604f4c0bdb19194a56c164b
Author: Corentin Noël <corentin noel collabora com>
Date:   Wed Dec 30 00:00:14 2020 +0100

    M!61 - Camel: Add several headers to provide GType for error domains
    
    It allows bindings to provide syntax sugar for GErrors
    glib-mkenums allows to get multiple headers to extract all the enums.
    
    Closes https://gitlab.gnome.org/GNOME/evolution-data-server/-/merge_requests/61
