             Summary: Add expression-level entry points to optimizer rules for the single-pass analyzer
                 Key: SPARK-58866
                 URL: https://issues.apache.org/jira/browse/SPARK-58866
             Project: Spark
          Issue Type: Task
          Components: Optimizer
    Affects Versions: 4.4.0
            Reporter: Matvei Zamiatin


The single-pass analyzer needs to run several optimizer rules on individual, freshly-resolved expression trees rather than on a whole LogicalPlan. For example, resolving a procedure CALL requires folding and rewriting its argument expressions (constant folding, With inlining, RuntimeReplaceable expansion, current date/time and current catalog/database substitution, special datetime values) before they are used.

Today these rules only expose plan-level apply(plan: LogicalPlan) entry points. This ticket refactors them to also expose expression-level entry points by extracting the shared rewrite logic into partial functions, with no behavior change to the existing plan-level apply.
