fix(ui): ext_cmdline should not move cursor to curwin

Problem:  The ext_cmdline cursor position on the screen seems to rely on
          an implicit assumption that the event listener implements a
          cmdline window that is made the current window which is
          problematic (e.g. breaks 'incsearch' in the actual current
          window).
Solution: Remove this assumption and allow nvim_win_set_cursor() to move
          the cursor on the screen to a non-current window (previous
          commit).
