change from kPlanB to kUnifiedPlan. Because of this, all uses of RTCConfiguration has to be updated to explicitly set the sdp_semantics field. The NO-OP version of this CL would be to set it to kPlanB and file a buganizer issue to track migration from kPlanB to kUnifiedPlan, but because nearby's use cases only uses data channels (i.e. it does not use WebRTC for audio and video) nearby should not care about which SDP semantics is used, and as such this CL goes ahead and updates it to kUnifiedPlan. For more info, see go/plan-b-removal-and-intro-to-unified-plan and b/208964426. PiperOrigin-RevId: 417348949
