UnmanagedType Specialization

[Akeit0]

Proposal of UnmanagedType Specialization

[MemoryPackable]
[Serializable]
public partial class Data<T>where T:unmanaged
{
   [MemoryPackUnmanaged]
    public T Value { get; protected set; } = default;
}

Then serializer use ReadUnmanaged/WriteUnmanaged.
Source generator can know whether generic T is unmanaged by ITypeSymbol.IsUnmanagedType.

Thanks for the suggestion.
For the benefits, there seem to be a lot of difficulties.

• The default LayoutKind for class seems to be different from struct.
• Also, MemoryPack provides higher version compatibility for classes than structs.
