vim-patch:8.2.4631: crash when switching window in BufWipeout autocommand

Browse Source 
Problem:    Crash when switching window in BufWipeout autocommand.
Solution:   Put any buffer in the window to avoid it being NULL.
            (closes vim/vim#10024)

win_init_empty() cannot be made static because it is used in autocmd.c
