vim-patch:9.1.1820: completion: some issues with 'acl' (#36007)

Browse Source 
Problem:  completion: some issues with 'acl' when "preinsert" and
          "longest" is in 'completeopt' (musonius, after v9.1.1638)
Solution: Fix various issues (see details below) (Girish Palya)

This commit addresses multiple issues in the 'autocompletedelay' behavior with
"preinsert" and "longest":

- Prevents spurious characters from being inserted.
- Ensures the completion menu is not shown until `autocompletedelay` has
  expired.
- Shows the "preinsert" effect immediately.
- Keeps the "preinsert" effect visible even when a character is deleted.

fixes: vim/vim#18443
closes: vim/vim#18460
