e412dd12e8 [chore](build) Use include-what-you-use to optimize includes (PART II) (#18761)
Currently, there are some useless includes in the codebase. We can use a tool named include-what-you-use to optimize these includes. By using a strict include-what-you-use policy, we can get lots of benefits from it.

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.
