#5544 Fix of Array of table is not sorted if Create<type>Direct() is used (#5546)

Browse Source 
* Fix C/C++ Create<Type>Direct with sorted vectors

If a struct has a key the vector has to be sorted. To sort the vector
you can't use "const".

* Changes due to code review

* Improve code readability
