[PT2][Optimus][Observability] Log the optimus graph transformation to the scuba (#119745)
Summary: Current everstore upload logging may cuase excessive compilation time when the model has lots of graph breaks (post: https://fb.workplace.com/groups/257735836456307/permalink/633533465543207/), we here log the transformation only when the graph changed
