gnu: Add home-gcr-ssh-agent-service-type.

GNOME Keyring used to be able to act as a wrapper over ssh-agent.
It would display a GUI password entry dialog, including a checkbox to remember
the password, which, if selected, would allow fully passwordless use of that key.

The SSH functionality is disabled by default in gnome-keyring-daemon
builds since version 1.46
(commit 25c5a1982467802fa12c6852b03c57924553ba73).
It has been moved
(https://gitlab.gnome.org/GNOME/gcr/-/merge_requests/67)
into gcr-ssh-agent, which is part of the gcr package.

* gnu/home/services/gnome.scm: New file.
(gcr-ssh-agent-log-file,gcr-ssh-agent-shepherd-services): New public
procedures.
(gcr-ssh-agent-configuration): New configuration record.
(home-gcr-ssh-agent-service-type): New service type.
* gnu/local.mk: Add it.
* doc/guix.texi: Document it.
