cc: Add command line for frame production throttle.
This CL decouples "disable gpu vsync" and "throttle frame production".
1. Add options of display-gpu-vsync
--disable-gpu-vsync=gpu : Sets |disable_display_vsync| true.
--disable-gpu-vsync=beginframe : Sets |throttle_frame_production| false.
--disable-gpu-vsync : Same as using both flags above.
2. Rename |disable_gpu_vsync| variable to |disable_display_vsync|.
