1, Emulate the quantize operation whose calculation follows the
expression clamp(tfl.round(input / scale) + zeroPoint, 0, 255).
2, Support pre-channel quantization and dequantization
3, Support int4 dequantization, but quantization operation doesn't
support int4 for tfl.quantize operator and it can't be emulated
because the cast operation also doesn't support int4.
