Added image data value to 'forEachLayerAtPixel' method callback

Browse Source 
The update has been added to the docs for all 'forEachLayerAtPixel' definitions
and currently returns null for non-supporting definitions. ol.Color typeDef
was also updated to support Uint8Arrays & Uint8ClampedArrays as it is the
reference type for the addded argument #5586
