feat(iceberg): Support iceberg Hash function

[jinchengchenghh]

The iceberg hash use mumur3 hash, which aligns with https://github.com/aappleby/smhasher/blob/master/src/MurmurHash3.cpp, firstly, process every 4 bytes as a chunk, then process remaining bytes by XOR, sparksql also uses this hash algorithm but is different with processing remaining bytes, which combine the remaining bytes. Extract the common function hashInt64.
The iceberg mumur3 hash should be strictly with java implementation, then write by iceberg could read with iceberg Java, and the function call can also get the correct result.
The iceberg utility lib velox_functions_iceberg_util will be linked by iceberg connector write to do partition transform. facebookincubator#13874
