gpu: Use ABOVE_NORMAL_PRIORITY_CLASS for gpu process
HIGH_PRIORITY_CLASS uses priority level 10 for THREAD_PRIORITY_LOWEST,
which is higher than THREAD_PRIORITY_NORMAL (8) used by most Chrome
threads. ABOVE_NORMAL_PRIORITY_CLASS should give us the same benefit
without the drawbacks. This only affects the GpuProcessHighPriorityWin
experiment.
