Fixes: #4207
C# uses a pseudo custom attribute serializableattribute to tell the compiler to set the serializable bit for managed types.
F# doesn't ...
By default F# marks managed types as serializable unless the type is decorated with SerializeableAuto(false) attribute.
The F# compiler used the presence of serializable attribute in the targetframework to determine whether there was any point setting the serializable bit. Given that the Managed assemblies are now usable across multiple platforms that may or may not support serialization. This PR modifies the compiler to always set the serialization bit, regardless of the compilation target profile.
With this change it should be possible to serialize / de-serialize libraries F# types compiled targeting netstandard 1.6 when used with an app targeting netstandard 2.0 + or net45+
A consequence of this change is that FSharp.Core for netstandard1.6 built with an updated compiler will obviously contain serializable types.
The change consists of a few small changes ..
Where serializable was determined by the presence of the serializable attribute in the target framework they now just use true.
The decision to set the serializable bit is now solely based on the absence of the AutoSerializationAttribute with the false parameter.
The code that emits serialization helpers are emitted based on the presences of SerializationInfo and SerializationContext. They are present in netstandard1.0, netcoreapp1.0, net45 and all subsequent frameworks.
