add bi-laterial filter for denoise feature

bi-laterial was an algorithm published on Proceedings of the 1998 IEEE
 International Conference on Computer Vision, Bombay,India
The paper name is "Bilateral Filtering for Gray and Color Images"

It can smooths images while preserving edges, by means of a nonlinear
 combination of nearby image values. It was broadly used in camera for the
 features like "buity your skin" or "denoise".

This patch provided an CL implementation with 5x5 window size.

Test Usage: ./test-cl-image -f RGBA -t denoise -i <inputfile> -o <outputfiile>
