Fix overeager pre-delayed-EOL wrapping in AdaptDispatch (#18899)

Browse Source 
AdaptDispatch has a TODO item indicating that we should *not* consider a
row wrapped until we write into the cell beyond it. We actually do have
that logic (it even refers to it!), but we still set the wrap flag when
we fill the final column.

We never removed it because it broke the old VT rendering-based ConPTY
implementation.

Now that VtEngine is gone, so can be this code and this strange
workaround for a problem nobody was quite sure what was.

This will fix, hopefully, the last of our exact line length write wrap
issues. tmux users can finally rejoice.
