[csharp] flatc should generate a 'Create…' method for tables with struct field… (#5818)

* flatc should generate a 'Create…' method for tables with struct fields when also generating the object based api (C#)
https://stackoverflow.com/questions/60724317/flatc-should-generate-a-create-method-for-tables-with-struct-fields-when-al

* missing namespace fixed: C:\projects\flatbuffers\tests\namespace_test\NamespaceA\TableInFirstNS.cs(30,7): error CS0246: The type or namespace name 'StructInNestedNST' could not be found (are you missing a using directive or an assembly reference?)
