spaces-x bea9a7ba4f [feature] Support pre-aggregation for quantile type (#8234) ...

Add a new column-type to speed up the approximation of quantiles.
1. The  new column-type is named `quantile_state` with fixed aggregation function `quantile_union`, which stores the intermediate results of pre-aggregated approximation calculations for quantiles.
2. support pre-aggregation of new column-type and quantile_state related functions.
