Remove GSC usage from ExynosVideoDecodeAccelerator.

With support for compositing from GL_TEXTURE_EXTERNAL_OES image (and support
from the Exynos GL stack for creating those textures), the video decoder
does not have to perform an explicit YUV->RGB color conversion step.

+27% throughput on birds0.h264 through vda_unittest.
