docs: standardize GstCapsFeatures, GstChildProxy documentation
* Don't mention explicitly that API is MT safe, this implies that other API is not. GStreamer API is assumed to be MT safe, thread safety should only be explicitly mentioned when API is *not* MT safe * Document virtual methods in standalone comments, in order to properly annotate them * Don't repeat what annotations are stating with respect to ownership transfer, nullability * Misc cleanup / typo fixes / addition of links Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/755>
