vim-patch:9.1.0009: Cannot easily get the list of matches (#27028)

Problem:  Cannot easily get the list of matches
Solution: Add the matchstrlist() and matchbufline() Vim script
          functions (Yegappan Lakshmanan)

closes: vim/vim#13766

Omit CHECK_LIST_MATERIALIZE(): it populates a List with numbers only,
and there is a check for strings below.
