Remove unused serialization members (#22785)

* Remove unused serialization members

* Remove unused S.Security.Permissions serialization test code

* Remove duplicate test code. S.Drawing.Primitive type serialization is already throughly tested in S.Runtime.Serialization.Formatters.Tests

* Remove ConcurrentBag unused serialization code

* Removing unused Principal/Identity serialization code
