C# 9 allows for T? on types that are not known to be reference or value types. This reduces the need to use nullability attributes.

For instance void M<T>([AllowNull]T value) can now be expressed with void M<T>(T? value).

We could create an analyzer/fixer pair to help users migrate to the more modern and concise style.

Relates to #48023 (which is now closed and was attempting to solve that problem a different way)
