We shouldn't return unknown. Find the right profile. Remove this.

This can also go to gpu_video_accelerator_unit.h/.cc.
gpu_video_accelerator_util.h can be in content/common/gpu/media instead.

Or maybe we want to move all ConvertMediaToGpuProfiles and
ConvertGpuToMediaProfiles to gpu_video_accelerator_util.h?
