bug#61525: 29.0.60; delete-frame will raise frames in another virtual desktop

[Kai Ma]

On MacOS, delete-frame can raise a frame in another virtual desktop,
which will cause switching between desktops.  This is annoying,
especially for emacsclient users.

To quote frame.c:

#ifdef NS_IMPL_COCOA
      else
        /* Under NS, there is no system mechanism for choosing a new
           window to get focus -- it is left to application code.
           So the portion of THIS application interfacing with NS
           needs to know about it.  We call Fraise_frame, but the
           purpose is really to transfer focus.  */
        Fraise_frame (frame1);
#endif

However, this has an undesired side effect: the desktop will be
switched.

Steps to reproduce:

1. Run emacs.
2. C-x 5 2, and move the new frame to another desktop.
3. C-x 5 0.  Now you see the desktop is switched.

This is a known issue for some time [1] and there is a patch that simply
disables raise_frame [2].  I'm not sure whether this patch is entirely
correct (and I think not).  But I do think the behavior should be
improved; at least the undesired desktop switching should be avoided.

Best regards,
Kai
