vim-patch:9.1.0381: cbuffer and similar commands don't accept a range (#28571)

Problem:  cbuffer and similar quickfix and locationlist commands don't
          accept a range, even so it is documented they should
          (ilan-schemoul, after 8.1.1241)
Solution: Define ex commands with ADDR_LINES instead of ADDR_OTHER

fixes: vim/vim#14638
closes: vim/vim#14657
