Refactor code in wxQuantize() for MSVC to avoid crash

Browse Source 
VC++ compilers (at least up to VS 2015) seem to generate incorrect code for the dithering code taken from libjpeg (pass2_fs_dither() function), where it is known to create problems too.
Refactor the code to avoid invalid optimization in this function and turn optimization on.

Closes #17764.
