This commit adds `sb()->create_object()`, `sb()->get_object()`, `sb()->check_object_type()` and `sb()->destroy_object()` in libretro builds to keep track of all C++ objects allocated by the bindings in libretro builds. This has some benefits: * Any C++ objects allocated by the bindings that are still alive when the game terminates can now be deallocated instead of being leaked like before. * We now keep track of the types of all objects allocated by the bindings, so we will be able to detect when the bindings attempt to access objects of mismatching type. * Keeping track of all allocated objects is required to implement libretro save states. * Objects are now kept track of using numeric keys whose sizes are the same on every platform rather than pointers, which helps with making save states portable across platforms.
