COMPMID-1410 (Nightly) Mismatches in CLMeanStd function for float

Change CLReductionOperation border to be multiple of 64 instead of 16.
The opencl kernel works only with local_size(0) being a power of 2. This will
generate a padding of 63 if input_width % 64 = 1, but I don't think it's a
big issue and it keeps the border calculation pretty simple.

Also, increased tolerance for fp32 because there were mismatches
for the 4K image.
