PERF: Update all user_histories with one query in UserDestroyer (#16717)
7a284164 previously switched the UserDestroyer to use find_each when iterating over UserHistory records. Unfortunately, since this logic is wrapped in a transaction, this didn't actually solve the memory usage problem. ActiveRecord maintains references to all modified models within a transaction.

This commit updates the logic to use a single SQL query, rather than updating models one-by-one
