x11: Remove deprecated/defunct X11 hints

Browse Source 
SDL_HINT_VIDEO_X11_FORCE_EGL was deprecated in favor of the more general SDL_HINT_VIDEO_FORCE_EGL, and Xinerama and Xvidmode support was previously removed from SDL, rendering their associated hints nonfunctional.

SDL_SetWindowBrightness and SDL_SetWindowGammaRamp have been removed from the API, because they interact poorly with modern operating systems and aren't able to limit their effects to the SDL window.
Programs which have access to shaders can implement more robust versions of those functions using custom shader code rendered as a post-process effect.
## SDL_hints.h
The following hints have been removed:
* SDL_HINT_VIDEO_X11_FORCE_EGL (use SDL_HINT_VIDEO_FORCE_EGL instead)
* SDL_HINT_VIDEO_X11_XINERAMA (Xinerama no longer supported by the X11 backend)
* SDL_HINT_VIDEO_X11_XVIDMODE (Xvidmode no longer supported by the X11 backend)
