* lisp/progmodes/project.el (project--other-place-prefix): New function.

(project-other-window-command, project-other-frame-command)
(project-other-tab-command): Use it in Emacs versions not less than 30
where other-*-prefix commands are available.
This fixes the cases such as 'C-u C-x 5 p p f TAB' from bug#65558.
