Ignore dedicated windows in 'display-buffer-reuse-mode-window'

Ignore the dedicated windows unless the dedicated window is
already displaying the buffer-to-be-displayed.  In that case,
the window may be reused, according to the setting of
'inhibit-same-window'.
* lisp/window.el (display-buffer-reuse-mode-window): Check
'window-dedicated-p' before pushing the candidate window onto
the stack.  (Bug#76216)
