IVGCVSW-3228 Fix bias quantization to be INT32 not QAsymm8
* Add function to calculate bias tensor quantization scale
from input and weights scales.
* Change visitor method of Conv2d, DepthwiseConv and FullyConnected to use
the new function.
* Fix Unit tests to expect correctly calculated quantization parameters.
