Feature: Spill Index File

[Xuanwo]

Summary

Databend generates numerous temporary files when spilling. Currently, we use list_objects to retrieve the complete list and then call delete_objects, which involves many costly list_objects calls.

Therefore, I propose introducing a spill index file to record all temporary files created. This would allow us to remove them by reading this file's contents instead of using list_objects.
