Move EventStreamInfo, EventFormat, CutBookkeeper, and ByteStreamMetadata to use GenericMetadataTool
As part of the move to AthenaMT the metadata tools have to conform to a new interface
- put input data in MetaCont containers which can be accessed based on EventContext
- avoid incidents where possible
- provide output consistent with existing use cases This requires changes to all the metadata tools. This is a migration of some of them to a new generic metadata tool which reduces the code duplication in existing tools
