patch 9.1.1435: completion: various flaws in fuzzy completion

Problem:  completion: various flaws in fuzzy completion
Solution: fix the issues (Girish Palya)

- Remove the brittle `qsort()` on `compl_match_array`.
- Add a stable, non-recursive `mergesort` for the internal doubly
  linked list of matches.
- The sort now happens directly on the internal representation (`compl_T`),
  preserving sync with external structures and making sorting stable.
- Update fuzzy match logic to enforce `max_matches` limits after
  sorting.
- Remove `trim_compl_match_array()`, which is no longer necessary.
- Fixe test failures by correctly setting `selected` index and
  maintaining match consistency.
- Introduce `mergesort_list()` in `misc2.c`, which operates generically
  over doubly linked lists.
- Remove `pum_score` and `pum_idx` variables

fixes: #17387
closes: #17430
