Changes to Aggregate Functions and Bug Fixes in ClickHouse

You can no longer use the aggregate function avgWeighted with arguments of type Decimal. Workaround: convert arguments to Float64. This closes #43928. This closes #31768. This closes #56435. If you have used this function inside materialized views or projections with Decimal arguments, contact [email protected]. Fixed error in aggregate function sumMap and made it slower around 1.5..2 times. It does not matter because the function is garbage anyway. This closes #54955. This closes #53134. This closes #55148. Fix a bug in function groupArraySample - it used the same random seed in case more than one aggregate state is generated in a query. #56350 (Alexey Milovidov).
