Reduce hash correlations when partitioning keys for aggregation (#42547)
Untangle hash calculation from the hash map. Also allocate distinct bit ranges for different use cases (upper 32 bits: hash map cell; next 16 bits: spilling bucket; lower 16 bits: hash shuffle). Fix the ui32 multiplication overflow. Add the hashing quality test.
