7. Add samplerExternalOES, sampler2dRect target and NV12 format support … …

   …in ps_yuv_image.
   
   Use WR_FEATURE_TEXTURE_EXTERNAL for samplerExternalOES support.
   Use WR_FEATURE_TEXTURE_RECT for sampler2dRect support.
   Use WR_FEATURE_NV12 for NV12 format support.
   The WR_FEATURE_TEXTURE_EXTERNAL and WR_FEATURE_TEXTURE_RECT are exclusive.

13. Create the ps_image and ps_yuv_image arrays for different feature set… …

    …tings.
    
    Each feature combination has its shader object in the array. We will select the correct one according the image_buffer_kind, format and color_space properties.

15. Set default yuv color space setting in ps_yuv_image. …

    The angle_shader_validation doesn't set any feature string for shader.
    So, the color_matrix is not defined. Set REC601 as the default value.
