bitexact gaussianblur implementation (#10345)

Browse Source 
* Bit-exact implementation of GaussianBlur smoothing

* Added universal intrinsics based implementation for bit-exact CV_8U GaussianBlur smoothing.

* Added parallel_for to evaluation of bit-exact GaussianBlur

* Added custom implementations for 3x3 and 5x5 bit-exact GaussianBlur
