Performance Increase of Vector of Structures using .NET BlockCopy (#4830)

* Added Get<vector_name>Array() method for accessing vectors of structures in C# using Buffer.Blockcopy().

* Added Get<vector_name>Array() method for accessing vectors of structures in C# using Buffer.Blockcopy().

Added Create<Name>VectorBlock() method to add a typed array using Buffer.BlockCopy() to speed up creation of vector of arrays

New Lua files for namespace test

* fixed c++ style issue
