Error NU3001 has 7 scenarios causing maintainability issues

[kartheekp-ms]

NU3001 error code has 7 scenarios where few of them are dependent upon Exception.HResult Property causing maintainability issues.

For e.g. https://github.com/NuGet/NuGet.Client/blob/eb9ad919724e5ef435d6321b775868c9f2c0f9a2/src/NuGet.Core/NuGet.Commands/SignCommand/CertificateProvider.cs#L59-L90

This logic broke tests in package signing logic when dotnet returns a different HRResult value. For e.g. #9523

As per dotnet/runtime#36786 (comment), dotnet doesnot guarantee the HResult values of most of our exceptions, depending on them is going to be fragile..

We need to re-evaluate all the 7 scenarios of NU3001 error code and implement code that doesn't reply on Exception.HRResult if possible.
