Currently, Memo is only using the first event (in event cache).
But to support carry over memo when continueAsNew, describeWorkflow with memo, and update memo in workflow, we need to add it to mutable state.
This PR add memo to mutable state and use it in transferQueue.
We can think about doing similar thing for ExecutionTime if needed for describe.
