  timer: Added SDL_GetTicks64(), for a timer that doesn't wrap every ~49 days.
  
  Note that this removes the timeGetTime() fallback on Windows; it is a
  32-bit counter and SDL2 should never choose to use it, as it only is needed
  if QueryPerformanceCounter() isn't available, and QPC is _always_ available
  on Windows XP and later.
  
  OS/2 has a similar situation, but since it isn't clear to me that similar
  promises can be made about DosTmrQueryTime() even in modern times, I decided
  to leave the fallback in, with some heroic measures added to try to provide a
  true 64-bit tick counter despite the 49-day wraparound. That approach can
  migrate to Windows too, if we discover some truly broken install that doesn't
  have QPC and still depends on timeGetTime().
  
  Fixes #4870.
