Added Base_Hook::get_lib_name to track what renderer is hooked for overlay.
Objects used to detect renderer type are now also used to hook the rendering functions. So we don't have to build another device.
Updated VTables for DX12.
Some games doesn't initialise Steam before initalizing their Renderer (even if the doc says to) . So instead of waiting for the game to initialize it, hook to the rendering functions and deduce which implementation should be used.
