[dotnet-trace] Support automatic roll-over on trace files

We had a couple of internal teams interested in a feature for dotnet-trace where it would roll over after a specific amount of data has been written. i.e. it limits the result trace file size to a specified amount and it would roll over to another file or stop collecting.

A related feature request was adding a feature for leaving it on all the time but having the "latest X byte" to be written instead.
