Configure MSBuild debug path and save any logs

We have had many problems in the CI with MSBuild failing, and not
capturing the failure logs.

See https://github.com/dotnet/coreclr/issues/20236.

So, for all msbuild invocations, set MSBUILDDEBUGPATH to a new,
distinguished, subdirectory of the bin\Logs directory, named
"MsbuildDebugLogs". Change the CI to upload any log files found
there.
