This patch adds Interpolation kernels in **MicroBenchmarks/ImageProcessing** directory
It contains the implementation of bicubic and bilinear interpolation (sources mentioned in corresponding kernel files)
Since there was no license mentioned in either of reference, I have not added any license (but still mentioned them in corresponding kernel files).

Runtime: (Using https://reviews.llvm.org/owners/package/3/ flag)
