patch 9.1.0048: Abort opening cmdwin if autocmds screw things up

patch 9.1.0048: Abort opening cmdwin if autocmds screw things up
Problem: Autocmds triggered from opening the cmdwin (in win_split and
do_ecmd) can cause issues such as E199, as the current checks
are insufficient.
Solution: Commands executed from the cmdwin apply to the old curwin/buf,
so they should be kept in a "suspended" state; abort if
they've changed. Also abort if cmdwin/buf was tampered with,
and check that curwin is correct. Try to clean up the cmdwin
buffer (only if hidden and non-current to simplify things; the
same approach is used when closing cmdwin normally), and add a
beep. (Sean Dewar)
It'd be nice to also check that curwin was *really* created by win_split, as
autocommands can change curwin before it returns (so it can't be assumed to be
that of the split); for now, this means that the cmdwin may not be the botwin in
that case, which is probably OK.
closes: #12819
