Rooting serializable types for TrimTestBinaryDeserialization test

[LakshanF]

There is no reliable way for the trimmer to statically reach types that are needed for resource serialization and deserialization. The current plan is to keep all relevant library types that are serializable to get resources working with trimmed WinForms applications.

The first iteration of this effort is to root all types in runtime and windowsdesktop (with WindowsForms profile) assemblies that are serializable (except compiler generated types that are serializable). Additionally, there are couple of exceptions that are needed to be rooted for this test application to run in a trimmed mode; All of mscorlib assembly is rooted and a couple of additional types in the System.Resources.Extensions assembly (DeserializingResourceReader, RuntimeResourceSet).

Future iterations should look at more simple WinForms applications with custom resources to identify a core set of library types that need to be keep for basic WinForms applications with custom resources to be trimmed.
