COMPMID-1918: Different qinfos support in CLConcatLayer

Added support in CLDepthConcatenateLayerKernel and CLWidthConcatenateLayer for different
quantization arguments both for the input and output. If input's quantization infos are not
homogeneous the input values are requantized using the output's quantization info.
