This PR extracts fixed point multiplication in qnn.requantize into util.cc so that it can be used in other places like relay::quantize::QuantizeRealize

Please review @anijain2305@zhiics

Another comment - Currently, QNN includes headers (code) from Relay. I tried to make it as uni-directional as possible. However, this will create bi-directional code inclusion (which might be ok). Therefore, it is worth thinking if we should put FixedPointMultiply in some header in Relay, which QNN can now read from.

LGTM. Or we can just add a util.h header to put the declarations.

@zhiics Can you approve? Or shall we move FixedPointMul to relay/quantize/util.cc ?
