Description

### Is your feature request related to a problem or challenge?

This is a collection of various items related to "dynamic filtering"

Roughly speaking dynamic filters are filters who values are known during runtime but not planning (for example from the values of [topk](https://github.com/apache/datafusion/issues/15037))

Here is some more background:
* [Snowflake blog: Reimagining Top-K Aggregation Optimization at Snowflake](https://www.snowflake.com/en/engineering-blog/optimizing-top-k-aggregation-snowflake)
* [Dynamic Filters in Starburst](https://docs.starburst.io/latest/admin/dynamic-filtering.html),
