Add ambiguous check when generate join plan

[ygf11]

Describe the bug
For some join sql whose meaning is not clear, datafusion will not throw error.
For example, test0 and test1 both has c0 column.

❯ explain select * from test0 as t0 inner join test0 as t1 on c0 = c0;

In PostgreSQL, this will throw an error:

psql -d "$POSTGRES_DB" -h "$POSTGRES_HOST" -p "$POSTGRES_PORT" -U "$POSTGRES_USER" -c "explain select * from test0 as t0 inner join test0 as t1 on c0 = c0;"
ERROR:  column reference "c0" is ambiguous
LINE 1: ...select * from test0 as t0 inner join test0 as t1 on c0 = c0;
                                                               ^

The semantics of this sql is not clear, we need throw exception like PostgreSQL do.

To Reproduce
test0 and test1 both has c0 column.

Then run explain select * from test0 as t0 inner join test0 as t1 on c0 = c0;.

Expected behavior
