mesa/formatquery: Added COLOR_ENCODING <pname> query.

Browse source 
From the ARB_internalformat_query2 specification:

   "- COLOR_ENCODING: The color encoding for the resource is returned in
      <params>.  Possible values for color buffers are LINEAR or SRGB,
      for linear or sRGB-encoded color components, respectively. For non-color
      formats (such as depth or stencil), or for unsupported resources,
      the value NONE is returned."
