Diagnostics Repo Engineering Summary

[mikem8361]

A catch all and list of all the diagnostics repo engineering issues:

• Upgrade to .NET 9 SDK #4421
• Test against the .NET 9 runtimes
• Drop hosting on and testing against 7.0
• Add test.cmd/.sh option to just install the test runtimes and run all the tests.
• Build/test SOS for the s390x, riscv64 and ppc64le architectures: Where can I find dotnet-sos or libsos.so for linux-s390x and linux-ppc64le? #4494
• Test against the latest cdb debugger
• Sync/merge PAL/UtilCode changes from the latest runtime repo. Add utf16_* library.
• Update System.CommandLine version
• Investigate why the SOS tests on MacOS take so long (and sometimes time out)
• Move the symstore repo to diagnostics
• Remove the $(_BuildDisplayName) from build.yml
• Separate the test portion of build.yml into test.yml if practical
• Create reliable and tested scripts, etc. to generate test asset dumps for Microsoft.Diagnostics.DebugServices.UnitTests.
• Add newer Ubuntu images to testing workflows. #3882
• Separate the build legs/steps from the test ones
• Create our own RemoteExecutor that allows the SDK/runtime to be specified (.dotnet-test in our case)
• Use dotnet test from the .dotnet-test install to run tests on the current SDK and runtimes
• Remove installing test runtimes in global.json
• Convert all the test legs to Helix #165
• Unified Build control update #3331
• Specify all source-built dependencies and ensure they are regularly updated #3326
• [macos] Shipping dotnet-* tools unsigned  #1942
• Signing failures are not treated as fatal #1005
• Make sure we are properly publishing bundled-tools symbols #1631
• Consider adding GenApiCompat to check for API compatibility for Microsoft.Diagnostics.NETCore.Client #1803
• Reenable TestDbgEng tests in M.D.DebugServices.UnitTests #3111
• C++ header files for compiling profiler are obsolete #3551
• clang-cl support in C++ profiler headers #3552
• Convert SOS.Package project files to how dbgshim is packaged #2865
