[BinFmt] Support extended messages in binary log and binary viewer #9091
Description
#8917 will introduce new internal EventArgs Extended*EventArgs
In context of PR such events are stored in binary log as existing corresponding non extended *EventArgs.
As there is certain value in showing exteneded event data in binary log we need to:
- create new binary log events
- de/ser those
- bump up
FileFormat - facilitate updating binary log viewer to support those
