gstreamer: Implement element EOS handling
This commit implements EOS handling for events sent to the libcamerasrc element by the send_event method (which can happen when pressing Ctrl-C while running gst-launch-1.0 -e, see below). EOS events from downstream elements returning GST_FLOW_EOS are not considered here. To archive this add a function for the send_event method which handles the GST_EVENT_EOS event. This function will set an atomic to the received event and push this EOS event to all source pads in the running task. Also set the GST_ELEMENT_FLAG_SOURCE flag to identify libcamerasrc as a source element which enables it to receive EOS events sent to the (pipeline) bin containing it. This in turn enables libcamerasrc to receive EOS events, for example, from gst-launch-1.0 with the -e (--eos-on-shutdown) flag applied.
