Removed SDL_GetDisplayDPI()

Browse source 
This function wasn't consistently correct across platforms and devices.

If you want the UI scale factor, you can use display_scale in the structure returned by SDL_GetDesktopDisplayMode(). If you need an approximate DPI, you can multiply this value times 160 on iPhone and Android, and 96 on other platforms.
