Use generic Marshal.OffsetOf for closed source struct types

Proprietary

Replace resolved OffsetOf(typeof(T), fieldName) with the generic forwarding overload for closed source struct types on known .NET Framework 4.5.1+, .NET Standard 1.2+ or .NET Core 1.0+ targets. Preserve the field expression and marshalling layout; retain type variables, constructed generics, ref structs, old language syntax, shadows, comments and conditional snapshots.
