GpuScheduler fix:

- Ganesh generates a lot of cheap GL commands, so 100 commands were executing in 50us, causing us to spin on PostTask(ProcessCommands) 60+ times per frame. This change simply tracks the elapsed time after each 100 commands - if the time is less than 2ms, it continues on to the next 100 commands.

BUG=83628
TEST=trace FishIE demo with 500 fish, check that ProcessCommands is not called ~60 times per frame.
