Full Changelog: v3.2.1...v3.2.2

Native and R2R Symbol Download and Parsing Now Available
As of this release, if you capture a trace using dotnet-trace collect-linux or record-trace, native and R2R symbols can now be downloaded and resolved at analysis time. All .NET symbols (both native and R2R) are available on the Microsoft Symbol Server. Additionally, many Azure Linux symbol files are available on the Microsoft Symbol Server. For those targeting other distros, PerfView and TraceEvent are capable of pulling those symbol files from local directories by adding a local symbol path pointing to the files.
Most of the work for this was completed in PerfView and TraceEvent 3.2.1 with the final required fixes present in this release.
