When playing a SDR video after playing a HDR video, GPU process will
crash on Intel platform. The root cause is Chrome sets different color
space in VP without reset VP, which will cause something wrong happens
in VP.

This CL provides a fix that VP will reset when input/output color space
changes. What's more, color space will be set to VP only when it
changes, which reduces frequency of calling
VideoProcessorSetStream/*Output*/ColorSpace1()
