Instead of having each tracer implement its own parameter parsing, centralize the handling in the tracer subsystem using GstStructure. This simplifies tracer implementations and provides a consistent way to handle properties. It also allows for much better documentation by forcing tracer object to expose properties Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/8086>
