Update files cloned from PerfView

[cshung]

This is a work in progress.

My goal was to port these changes over, but I figured according to the documentation, the intent is to maintain a mirror, so I just copied all files over and see what happens.

No wonder - it won't compile - what should we do here?

@brianrob. It appears that some changes are good to have (e.g. the very large graph support, the gen4 support). However, the new version accessed types cannot be accessed here. Do you have some idea what shall we do with that?

@cshung I don't recall why, but these files are copied from the perfview repo. There have been a number of changes that likely impact other files (e.g. there is a new type called SerializationConfiguration, a new enum called StreamLabelWidth). Perhaps it would be worth revisiting if the TraceEvent NuGet package can be used directly, or what it would take to get there. Alternatively, you'll have to go through each of these errors and figure out which files are missing - for example SerializationConfiguration is part of FastSerialization.
