API: make nvim_win_set_option() set window-global, not buffer-local #9110

Browse Source 
NB: the `!(flags & SOPT_GLOBAL)` exception is for 'statusline'.
Because `:set statusline=...` sets the global value for _all_ windows,
`:setlocal` is the best we can do there. This is a one-of-a-kind option
that doesn't work like any other option.
