Query Reporting: Remove old query_recorder

What does this MR do and why?

We added recording of queries using auto_explain in !125454 (merged), and the artifacts we generate there can be used to solve the same use-case as the query recorder added in !100335 (merged), so in this MR we are removing the older query recorder code in order to save disk space on the CI runners.
