  Use OES_texture_storage_multisample_2d_array
  
  There's an OES extension for multisample texture arrays,
  OES_texture_storage_multisample_2d_array. Change references from
  ANGLE_texture_multisample_array to the native extension in the shader
  compiler.
  
  ANGLE still needs to have robust behavior for out-of-range texel
  fetches that's not found in the original extension, but this does not
  need to be spelled out in the extension spec.
