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 Bug: b/376300037 Change-Id: I63ef75fe342b149336c0e274bd9cbf6c3aa34c23 Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/6072435 Commit-Queue: Roman Lavrov <romanl@google.com> Reviewed-by: Cody Northrop <cnorthrop@google.com>
