Bump Microsoft.Diagnostics.Tracing.TraceEvent to 3.1.28 and update dotnet-trace for NetTrace v6 support

[Copilot]

Fixes #5610

Updates TraceEvent package to enable NetTrace v6 format with thread time samples and updates dotnet-trace convert and dotnet-trace report commands to handle .nettrace files generated by dotnet-trace collect-linux.

Changes

• Updated MicrosoftDiagnosticsTracingTraceEventVersion in eng/Versions.props: 3.1.23 → 3.1.28
• Updated dotnet-trace convert to use ThreadTimeStackComputer instead of SampleProfilerThreadTimeComputer
• Updated dotnet-trace report to use ThreadTimeStackComputer instead of SampleProfilerThreadTimeComputer
• Updated dependency versions to satisfy TraceEvent 3.1.28 requirements:
  • System.Text.Json: 8.0.5 → 9.0.8
  • System.Collections.Immutable: 8.0.0 → 9.0.8
  • System.Reflection.Metadata: 8.0.0 → 9.0.8
  • System.Text.Encodings.Web: 8.0.0 → 9.0.8

What this enables

NetTrace v6 adds:

• Thread time samples in multi-process traces (from dotnet-trace collect-linux)
• Improved metadata and label support (W3C TraceContext correlation)
• Better compression and memory efficiency
• Extended payload field types (VarInt, VarUInt, FixedLengthArray, etc.)

The ThreadTimeStackComputer class handles traces with thread time samples that don't have Microsoft-DotNETCore-SampleProfiler events, which is the case for .nettrace files generated by dotnet-trace collect-linux.

Affected components

• dotnet-trace convert and dotnet-trace report commands (now support collect-linux traces)
• All EventPipe-based tools: dotnet-counters, dotnet-gcdump, dotnet-stack, dotnet-dsrouter, and EventPipe monitoring libraries

See NetTrace v6 format spec for technical details.

Original prompt

Can you fix #5610. It involves bumping MicrosoftDiagnosticsTracingTraceEventVersion in eng/Versions.props to 3.1.28. The .nettrace generated by collect-linux is NetTrace v6 which is documented here https://github.com/microsoft/perfview/blob/main/src/TraceEvent/EventPipe/NetTraceFormat.md and there aren't any currently in the repository, so I would like to test it locally, or give you a .nettrace that has thread time samples.

@copilot #5610 requires changes to dotnet-trace convert and dotnet-trace report to use the ThreadTimeStackComputer that was added to Microsoft.Diagnostics.Tracing.TraceEvent.3.1.28.nupkg. The issue describes that .nettraces generated by dotnet-trace collect-linux will not have any samples from Microsoft-DotNETCore-SampleProfiler, which dotnet-trace convert and dotnet-trace report rely on. The goal is to extend dotnet-trace convert and dotnet-trace report to handle the thread time samples in a dotnet-trace collect-linux .nettrace by using the ThreadTimeStackComputer.

Updated dotnet-trace convert and dotnet-trace report to use ThreadTimeStackComputer instead of SampleProfilerThreadTimeComputer to handle thread time samples from collect-linux .nettrace files.

Also updated dependency versions (System.Text.Json, System.Collections.Immutable, System.Reflection.Metadata, System.Text.Encodings.Web) to 9.0.8 to satisfy TraceEvent 3.1.28 requirements.

@copilot Lets hold off on updating the PR for now, and lets just iterate on the files, check the changes without pushing commits. Can we do that?
I have a sample.nettrace that demonstrates the nettrace v6 with dynamic events that I want you to use to validate the fix. How can I get it to you?
The goal is to upgrade dotnet-trace convert and dotnet-trace report to be able to handle the new nettrace format, and be able to use the ThreadTimeStackComputer when appropriate. I dont quite understand why we need to update System.Text.Json, System.Collections.Immutable, System.Reflection.Metadata, and System.Text.Encodings.Web, can you explain how you got those dependency versions from TraceEvent 3.1.28?
