Traces generated by collect-linux in #5570 do not collect samples from Microsoft-DotNETCore-SampleProfiler. dotnet-trace convert and dotnet-trace report both generate thread time stacks assuming samples from SampleProfiler

and , so both verbs will result in empty thread time stacks.

Instead, collect-linux can collect thread time perf_event samples with --profile thread-time. So to add support for the new collect-linux traces, convert and report should probably be updated to use https://github.com/microsoft/perfview/blob/main/src/TraceEvent/Computers/ThreadTimeComputer.cs when that's released
