Subject: [PATCH] Adding a VmaVector constructor for C++11 compatibility

The std::vector constructor used (count + allocator) is only available in C++14 (see: https://en.cppreference.com/w/cpp/container/vector/vector) and compiling with C++11 and `VMA_USE_STL_VECTOR` will result in compile errors. This adds a new constructor and switches to using that for compatibility.
