Seungha Yang e006366206 d3d11decoder: Enable high precision clock if needed
We've been doing retry with 1ms sleep if DecoderBeginFrame()
returned E_PENDING which means application should call
DecoderBeginFrame() again because GPU is busy.
The 1ms sleep() during retry would result in usually about 15ms delay
in reality because of bad clock precision on Windows.
To improve throughput performance, this commit will enable
high precision clock only for NVIDIA platform since
DecoderBeginFrame() call on the other GPU vendors seems to
succeed without retry.
