MLBEDSW-4163: OFM zero point outside valid range
This commit fixes a bug where the OFM zero point
would assume values outside of [0, 255] due to it's
usage as a stand-in for a bias when emulating the
TensorFlow Lite implementation of MEAN.
The solution is to adjust for the bias using an
ADD operator with the bias value as an int16 const
tensor. The 16-bit integer is needed as the bias
is 32 bits in the original implementation but can
effectively assume values in the range [-255, 255].
