refactor: Integrate the materialized CTE into the plan and pipeline

[SkyFan2002]

I hereby agree to the terms of the CLA available at: https://docs.databend.com/dev/policies/cla/

Summary

This PR improves the execution of materialized CTEs. Previously, a temporary table was created in the bind phase. This had several drawbacks:

1. the CTE and main query couldn't be jointly optimized by the optimizer
2. the information from "explain" and "profile" is inaccurate
3. automatic memory spilling of materialized CTE at the query level wasn't possible.

The proposed changes allow for better integration of materialized CTEs into the planning and optimization stages.
