Byoungchan Lee 33728152ca Fix crash of ObjC SDK sLD / sRD with incorrect SDP.
There are two problems with setLocalDescription / setRemoteDescription
in ObjC SDK.
First, RTCSessionDescription.nativeDescription returns a raw
nullableSessionDescriptionInterface pointer, where sLD/sRD are calling
Clone() method unconditionally, so it might crash.
Second, unnecessary sLD/sRD calls Clone() of the raw pointer and
does not delete it, so this pointer will leak.

To solve these problems, I changed the return type of nativeDescription to
std::unique_ptr and removed the call to Clone() method.
