Shuo Wang d2d5c19d51 [Improvement](Nereids) Avoid unsafe cast. (#12603) ...

This PR changed some interfaces to avoid unsafe cast.

- Modify `Plan.getExpressions()`'s return type from `List<Expression>` to `List<? extends Expression>`
Return projects (type is a list of named expression) in `getExpressions` can avoid unsafe cast. See `LogicalProject.getExpression()` as an example.

- Modify `EmptyRelation.getProjects()`'s return type from `List<NamedExpression>` to `List<? extends NamedExpression>`
Creating empty relation with a list of slots can avoid unsafe cast. See the `EliminateLimit` rule for example.
