Review Comment:
could we not rely on `expr.toSql()`? because legacy planner's expr toSql is
not right in some corner cases. the other way is fix all problem in
`expr.toSql`.

what the different between this and createSlotDesc? could we merge them into
one function?

Review Comment:
we should throw AnalyzeExpression

Review Comment:
slotReplacer and a independent expression analyzer is little trick here.
maybe we need to adjust analyze order to avoid analyze expression in mulit
places?
- bind relation
- bind sink (create with unbound expression)
- analyze expression
- do sink cast or other things

Review Comment:
why create a new cascadesContext here? why not use context for this
statement?
