Feature request: implement secret service spec

[nim65s]

Hi,

Many desktop applications expect their secrets to be managed through DBus via https://specifications.freedesktop.org/secret-service-spec/latest. This specification is already implemented by gnome libsecret and KDE wallet.

This can probably be implemented with zbus, and API can be generated with zbus-xmlgen file org.freedesktop.Secrets.xml (that file is available here, except there is a typo).

Would this be considered in scope for this project ?

i'd be open to reviewing a pr for this, if someone is interested! i don't know anything about dbus though, so i'm unlikely to get to it myself anytime soon.
