Added more errors to GES_ERROR for when edits fail (other than programming or usage errors). Also promoted some GST messages if they related to a usage error. Also added explanation of timeline overlap rules in user docs. Part-of: <https://gitlab.freedesktop.org/gstreamer/gst-editing-services/-/merge_requests/177>
