Consolidate the UsageReport task logic between VMR and Arcade

VMR - https://github.com/dotnet/dotnet/tree/main/eng/tools/tasks/Microsoft.DotNet.UnifiedBuild.Tasks/UsageReport
Arcade - https://github.com/dotnet/arcade/tree/main/src/Microsoft.DotNet.SourceBuild/tasks/src/UsageReport

There are some difference but a lot the same.  It would be good to share the commonality.
