Better runtime error handling

[MichalLytek]

I like the idea presented in graphql-errors library, where runtime errors are captured and replaced with UUID to prevent data leaks:

Direct integration with this library might not be a good idea as its outdated but I think that the source code is simple and I can reimplement it in TypeGraphQL with better API that would allow to enable/disable it per type or field and pass custom mask function in decorators.
