MLBEDSW-11373: Calc scales for FCs with PC quant with high precision
TFLite FULLY CONNECTED with per-channel quantization should use double precision when converting to explicit scales. This differs slightly compared to TFLite FULLY CONNECTED with global quantization which should use single precision when converting to explicit scales.
