Verify SCCSID/debugging when VMR uses a single commit hash for every indvidual repo

@am11 [pointed out](https://github.com/dotnet/runtime/pull/100022#issuecomment-2010665752):

> Note that this script also updates [SCCSID](https://en.wikipedia.org/wiki/Source_Code_Control_System) in runtime and diagnostics repos and altering this will require retesting those scenarios end-to-end. In addition to bootstrapping, libSOS in diagnostics actually depends on the value of that sccsid[] in a way that it breaks the debugging functionality, so it is pretty vital. That's why we want to keep this non-msbuild version evaluation working.

We should verify this stays working.
