Hook_Manager now only manages hooks.
Renderer_Detector is used to detect the game's renderer. There will be 2 version of it. 1 for windows and 1 for Linux.
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.
With that change, I no longer re-hook rendering functions as Hook_Manager::FoundRenderer removes all hooks and then we hook the true functions in the renderer specialization.
Added a retry count.
Every class has a job. Overlay is to show an overlay not to hook windows functions.
Hook_Manager's job is to manage hooks and should not contain a reference to the overlay. (It should not contains any reference to directX or OpenGL either but I'll see that later... Maybe)
This makes the overlay code much cleaner and "could" be used in Linux as well.
