Misleading syntax error for import-as statement followed by erroneous statement on same line

Bug report

Bug description:

Currently we have:

>>> import typing as t; None = 1
  File "<python-input-0>", line 1
    import typing as t; None = 1
                     ^
SyntaxError: cannot use name as import target

which doesn't make sense. Prior to #123629, it was:

>>> import typing as t; None = 1
  File "<python-input-0>", line 1
    import typing as t; None = 1
                        ^^^^
SyntaxError: cannot assign to None

We should restore the old message for this case.

I have a patch ready.
