feat(emacs-pkgs/niri): functions for seamless niri/emacs switching r/8728

Introduces a new buffer switching function which is also capable of switching to
existing Emacs frames that already display the target buffer, or to other
windows displayed in the same Niri session.

Not all behaviour is done yet, and there's an explanatory comment in the package
with more details.
