Added SDL_HINT_IOS_HIDE_HOME_INDICATOR to determine how the home indicator on the iPhone X is handled.

Browse Source 
This variable can be set to the following values:
   "0"       - The indicator bar is not hidden (default for windowed applications)
   "1"       - The indicator bar is hidden and is shown when the screen is touched (useful for movie playback applications)
   "2"       - The indicator bar is dim and the first swipe makes it visible and the second swipe performs the "home" action (default for fullscreen applications)
