  Initial implementation of ANGLE_stream_producer_d3d_texture_nv12.
  
  Add the validation and entrypoints for
  ANGLE_stream_producer_d3d_texture_nv12, which is a new EGL extension
  currently being written. The purpose of this extension is to allow
  insertion of D3D11 NV12 textures to be inserted into a stream. This acts
  as the producer of the EGL stream.
