videorate: Fix changing rate property during playback
We need to take into account the base_ts to compute next_ts and it needs to be updated on rate change. This introduces `pending_rate` so that change rate is properly handled in the streaming thread in a safe way. Added tests Part-of: <https://gitlab.freedesktop.org/gstreamer/gst-plugins-base/-/merge_requests/679>
