 * @brief ConvertQuantizeDequantize transformation replaces following graph:
 * FakeQuantize->Convert->Convert->Subtract->Multiply with a single FakeQuantize.
 * Restrictions:
 * - quantized data type must be i8 or u8
 * - 'levels' attribute to FakeQuantize must be equal to 256
 * - (output_low, output_high) must be (-128, 127) or (0, 256) (depends on sign of quantized data type)
 * - 'zero_point' and 'scale' must be broadcastable to FakeQuantize's output
