I think we can simplify this by using the helper script from NativeAOT in DNNE:
AaronRobinsonMSFT/DNNE@master...am11:chore/use-nativeaot-helper-for-msvc. It basically uses vswhere to locate a working toolchain and has been working for 8+ years (dotnet/corert@9e2f015)

@AaronRobinsonMSFT, @jkoritzinsky wdyt? We can probably drop the ISetup fallback. If that script is good enough for NativeAOT publishing, it should be good enough for DNNE too. 👀
