  D3D: Add multiplanar support to d3d11 glTexSubImage2D
  
  Add multiplanar format support to Angle's D3D11 glTexSubImage2D.
  This is needed with multiplanar shared images, where we write all
  planes of a d3d shared image through WritePixelsYUV in raster decoder
  and need to do this via an intermediate texture for d3d11. This change
  checks for multiplanar format supported by Image11 and then goes
  through TextureD3D::commitRegion and performs copyTexture and then
  copySubResource.
  
  Added necessary test that tests for full texture copy and a subregion
  copy and reads back and verifies.
