C#: Avoid generic types in the script path attribute generator

- Avoid generic types in `ScriptPathAttributeGenerator`, this
means they won't be added to the `[AssemblyHasScripts]` attribute
and a `[ScriptPath]` attribute won't be added to the class.
Since generic classes can't be used as scripts they shouldn't use
those attributes, this also makes CSharpScript consider those types
invalid since they won't be added to the script/type map.
- Avoid generic types in `ScriptManagerBridge.LookupScriptsInAssembly`.
- Set `outMethodsDest` in `ScriptManagerBridge.UpdateScriptClassInfo`.
