Closes #608 Blocked by: https://github.com/rapidsai/cudf/issues/11515 Note: currently, performing multiple aggregations at once seems to result in incorrect values. Ex: `SELECT STDDEV(a) AS s1, STDDEV_POP(a) AS s2 FROM df` returns the...

#629 Implemented STDDEV_POP on cpu, but it currently fails on gpu due to: https://github.com/rapidsai/cudf/issues/11515#issuecomment-1212305118

**What happened**: Queries that include multiple distinct aggregations on the same column (ex: `SUM(a)` and `AVG(a)`) return incorrect results. **Minimal Complete Verifiable Example**: ```python import pandas as pd from dask_sql...
