[Breaking] Refactor Base Tracer(#4549)
### Refactor the BaseTracer - Remove the 'session' abstraction from the BaseTracer - Rename 'RunV2' object(s) to be called 'Run' objects (Rename previous Run objects to be RunV1 objects) - Ditto for sessions: TracerSession*V2 -> TracerSession* - Remove now deprecated conversion from v1 run objects to v2 run objects in LangChainTracerV2 - Add conversion from v2 run objects to v1 run objects in V1 tracertextloader_autodetect_encodings
