fix: show autocmd output when F is in shortmess (#18251)

The default value of including F in 'shortmess' has the unfortunate side
effect of hiding output from autocommands. This is a common source of
confusion and often leads people to think their autocommands are not
working when they are. There is a small snippet in the docs for
'shortmess' indicating that the F flag suppresses autocmd output, but
it's not easy to find if you don't already know to look for it.

This commit removes that behavior of the F flag to make it only suppress
file info when opening a new file.
