   Closes #11621.
   
   ## Rationale for this change
   Given an example query: 
   ```sql
   SELECT * FROM t1 JOIN t2 ON t1.v1 = t2.v1 WHERE (t1.v1 == t2.v1) OR t1.v1
   ```
   When removing the join predicate `t1.v1 = t2.v1` from the parent filter 
`(t1.v1 == t2.v1) OR t1.v1`,  this process can be considered as replacing the 
join predicate with `true`. The result should be `TRUE OR t1.v1` and further 
simplified to empty, but currently, it is `t1.v1`. This will lead to incorrect 
join results.
