added [DynamicallyAccessedMembers(DynamicallyAccessedMemberTypes.PublicFields)] annotations to generic enums

[filipw]

At the moment the build fails when using .NET SDK 7.0.100-rc.1
There is a trimming error:

/fido2-net-lib/Src/Fido2.Models/Converters/EnumNameMapper.cs(68,35): error IL2090: 'this' argument does not satisfy 'DynamicallyAccessedMemberTypes.PublicFields' in call to 'System.Type.GetFields(BindingFlags)'. The generic parameter 'TEnum' of 'Fido2NetLib.EnumNameMapper' does not have matching annotations. The source value must declare at least the same requirements as those declared on the target location it is assigned to. [/Users/filipw/Documents/dev/fido2-net-lib/Src/Fido2.Models/Fido2.Models.csproj::TargetFramework=net6.0]

This PR adds the necessary annotations.

Thank you @filipw. Looks good, will do a quick review and build/test on my machine before merging.

@filipw Every looks good. Merging. Where can I read more about the changes in .net 7 that causes these trimming issues?

[filipw]

There is some documentation around what to do in the library to prepare it for trimming here https://learn.microsoft.com/en-us/dotnet/core/deploying/trimming/prepare-libraries-for-trimming and it includes some info around these attributes. These are good practices to follow anyhow, but I am not sure why it suddenly showed up as error with .NET 7 SDK 🤷‍♂️
