Handle buffer-local 'window-size-change-functions' specially (Bug#32637)
* src/window.c (run_window_size_change_functions): Run a
buffer-local value once per each frame and only if at least
one window showing the buffer on that frame has changed its

* doc/lispref/windows.texi (Window Hooks): Describe new
behavior of buffer-local 'window-size-change-functions'.
