  Trace perf: add a basic fps limiter
  
  Adds sleeps based on each 4 frames timing (4 instead of just last frame
  makes fps a bit closer to requested)
  
  Example:
      --fps-limit=30
      *RESULT TracePerf_vulkan.wall_time: offscreen_bubble_shooter_and_friends= 33.3556469900 ms
      *RESULT TracePerf_vulkan.wall_time: bubble_shooter_and_friends= 33.4376432467 ms
  
      --fps-limit=50
      *RESULT TracePerf_vulkan.wall_time: offscreen_bubble_shooter_and_friends= 20.0218095000 ms
      *RESULT TracePerf_vulkan.wall_time: bubble_shooter_and_friends= 20.0624947200 ms
  
      --fps-limit=100
      *RESULT TracePerf_vulkan.wall_time: offscreen_bubble_shooter_and_friends= 10.1298787483 ms
      *RESULT TracePerf_vulkan.wall_time: bubble_shooter_and_friends= 10.1781205983 ms
  
      --fps-limit=200
      *RESULT TracePerf_vulkan.wall_time: offscreen_bubble_shooter_and_friends= 5.1289075067 ms
      *RESULT TracePerf_vulkan.wall_time: bubble_shooter_and_friends= 5.1571364367 ms
  
      --fps-limit=400
      *RESULT TracePerf_vulkan.wall_time: offscreen_bubble_shooter_and_friends= 2.6172564224 ms
      *RESULT TracePerf_vulkan.wall_time: bubble_shooter_and_friends= 2.7648291614 ms
