Timestamps are untouched by default, but the new mode can now be enabled to replace RTP timestamps with ones generated from the buffer PTS. Making it an enum in case different modes are needed in the future. That allows for a rtpjitterbuffer to do proper drift compensation, so that the stream coming out of gst-rtsp-server is not drifting compared to the pipeline clock and also not compared to the RTCP NTP times. Most of the code is borrowed from rtpbasepayload, as it's exactly its behaviour which I wanted to bring here. Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/7526>
