Use msbuild to build Az.Tools.Predictor.sln

[kceiw]

Description

dotnet msbuild is used in the pipeline to build the solution Az.Tools.Predictor.sln. That doesn't work with the workaround about transient dependencies on the source generator project. The workaround that work with dotnet msbuild doesn't work with msbuild either. See the issue here dotnet/sdk#17775. So in this change, I use mbuild to build the solution. That should make the build the same in the pipeline, command line on dev machine and Visual Studio on the dev machine.
