added D3D11 and D3D12 renderers from Emil/n64-fast3d-engine

Browse source 
along with options to select backends for windowing, rendering, audio and controls in the Makefile

use RENDER_API=D3D11 or D3D12 for the D3D renderers, that will also automatically enable using DXGI for windowing; SDL2 will still be used for input and audio for the time being

also adds three-point filtering to the OpenGL backend and an option for it in the menu
