Make 'clone-indirect-buffer-other-window' use other window

Make 'clone-indirect-buffer-other-window' use other window

Previously, depending on the settings in 'display-buffer-alist',
'clone-indirect-buffer-other-window' would display the cloned
buffer in the original window, behaving identically to
'clone-indirect-buffer' with a non-nil display-flag.  This
behavior was inconsistent with other-window commands which
always used another window.
Now, 'clone-indirect-buffer-other-window' uses
'switch-to-buffer-other-window'.  This means it uses the same
logic as other-window commands like 'find-file-other-window'
and 'info-other-window'.
display-flag was kept for API stability and functional
compatibility reasons.
* lisp/simple.el: (clone-indirect-buffer-other-window): Use
switch-to-buffer-other-window.  (Bug#70819)
