* [refactor](nereids) do not deny a runtime filter by removing an entry in aliasMap (#34559)
in current version, there are 2 approaches to verify whether a join condition can be used to generate a runtime filter, they are
1. remove the output slot from aliasMap
2. pushDownVisitor.visit(...) return false
the 1st approach has some drawbacks, we prefer to the 2ed approach.
In this pr, all the cases are handled by the 2ed approach, and remove the related code for the 1st approach.
