Rewrite Method Member Syntax Elements Tests and Refactor Method Member Syntax Elements

[alexanderlinne]

• Rewrite of the TypeSyntaxElementsTests similar to Add Tests For Object Predicates #393
• Refactoring of the Type Syntax Elements similar to Refactor Object Syntax Elements #414

Note: there are still two implementations of HaveReturnType/NotHaveReturnType to keep the current differences in how System.Type and IType are handled.
