feat(ui): use builtin completion popupmenu with ext_cmdline (#31269)

Browse Source 
Problem:  UIs implementing ext_cmdline/message must also implement
          ext_popupmenu in order to get cmdline completion with
          wildoptions+=pum.
Solution: Allow marking a window as the ext_cmdline window through
          nvim_open_win(), including prompt offset. Anchor the cmdline-
          completion popupmenu to this window.
