CMake test build projects pick up Arcade SDK

[mmitche]

When building a test project to determine the compiler, oddly enough CMake end up pulling in some Pdb2Pdb targets. This is pretty weird. Initial investigations seem to say that the custom SdkResolver causes this somehow. I'm still not sure why.

When resolved, remove the PublishWindowsPdb=false from repo-projects (sdk & deployment-tools).

@mmitche do we need to fix this for P4? https://github.com/dotnet/sdk/blob/11150c0ec9020625308edeec555a8b78dbfb2aa5/src/SourceBuild/content/repo-projects/sdk.proj#L76-L77

dotnet/roslyn#64581 (comment) implies that Windows PDBs don't need to be published anymore at all and should be disabled.
