Support binary search for struct in cpp (#4245)

* Support binary search for struct in cpp CreateVectorOfSortedStruct is provided for convenience. * fix continuous-integration error * add generated files * compile Ability.cs in csharp test * compile Ability.cs in csharp * modify according to code review
