`WebRTCSessionDescription` owns its `SDPMessage`. The `sdp()` accessor used to return a copy of the `SDPMessage` which prevented the user from getting a ref and by extension from getting a mutable ref for in-place modification. This commit makes the accessor return a reference to the inner `SDPMessage` and adds a mutable accessor. Previous behaviour (getting an owned copy of the `SDPMessage`) is available by calling `to_owned()` on the reference returned by `sdp()`. Users who wish to change the type of `WebRTCSessionDescription` can call `set_type()`. Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer-rs/-/merge_requests/1406>
