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.

changed title from d3d11decoder: Do retry DecoderBeginFrame() more aggressively to d3d11decoder: Enable high precision clock if needed

changed the description

This makes D3D11 decoder 3 times faster than before for some low-resolution streams on NVIDIA GPU. That makes sense because default Windows timer precision error can be up to about 15ms (15ms waiting for Sleep(1)!?!?)

Just a side track question, isn't there a concept a fence to fix this ?
