Avoid 3D video layer for GPU composition

Browse Source 
libhwcomposer: Donot mark the 3D layer below HWC_SKIP_LAYER
for GPU composition. In these cases, let the layer be
composed through composition type decided in hwc_prepare.
This helps us in avoiding the cases where 3D videos
cannot be composed through GPU.
