Instead of having a big list of features in the meson.build file, we reuse the information from the Cargo.toml files This refactors the dependencies to handle that new use case There were issue in previous handling and only activating the `webrtc` plugin was failing because the list of features incorrect. Fixes https://gitlab.freedesktop.org/gstreamer/gst-plugins-rs/-/issues/295 Part-of: <https://gitlab.freedesktop.org/gstreamer/gst-plugins-rs/-/merge_requests/1135>
