bug#32637: 27.0.50; window-size-change-functions not run from local hook

[Juri Linkov]

0. In emacs -Q open two windows: one with the *scratch* buffer,
another window with the *Messages* buffer with e.g. ‘C-h e’
(view-echo-area-messages).

1. In *scratch* eval:

(add-hook 'window-size-change-functions
          (lambda (frame) (message "%S" frame))
          nil t)

2. Resize windows with e.g. ‘C-x {’ (shrink-window-horizontally)
   Check the message with the frame name in *Messages*, fine.

3. Select the window with *Messages* with ‘C-x o’ (other-window),
   and resize again ‘C-x }’

No message in *Messages*, because the hook was not called,
but actually the size of the *scratch* buffer was changed.

window-size-change-functions needs to notify the buffer
that requested such notifications via this hook.
