Rollup merge of #93325 - tmiasko:lev, r=davidtwco
Introduce a limit to Levenshtein distance computation Incorporate distance limit from `find_best_match_for_name` directly into Levenshtein distance computation. Use the string size difference as a lower bound on the distance and exit early when it exceeds the specified limit. After finding a candidate within a limit, lower the limit further to restrict the search space.
