Support the bindings to be more integrable with a system's coherent memory management. Pleaes note that thorvg now only allow the desinated memory allocators here: malloc -> tvg::malloc calloc -> tvg::calloc realloc -> tvg::realloc free -> tvg::free issue: https://github.com/thorvg/thorvg/issues/2652
