Fix predicate to accept PPL Function inner node + update test expectations
PPL AstExpressionBuilder.visitWindowFunction wraps the parsed function in a WindowFunction whose inner is a Function, not an AggregateFunction (SQL emits AggregateFunction). The original predicate required AggregateFunction, so it returned false for every eventstats case and the rewrite never fired. Use BuiltinFunctionName.ofAggregation(funcName) so the predicate accepts both inner types, and convert Function to AggregateFunction in stripWindowFunctionForAggregate so aggVisitor resolves it the same way stats does. Test expectation adjustments observed from actual planner output: - IS NOT DISTINCT FROM: Calcite canonicalizes OR(=, AND(IS NULL, IS NULL)) to IS NOT DISTINCT FROM on nullable partition keys (DEPTNO in EMP). - Plain =: on non-nullable partition keys (server in POST.LOGS), RexSimplify drops the IS NULL conjuncts and leaves equality. - Outer Project folded for no-BY cases: the final passthrough projection is a no-op identity in the no-BY case and Calcite folds it; the BY case keeps the project because it drops the right-side group-key column. verifyPPLToSparkSQL calls in CalcitePPLEventstatsEarliestLatestTest are removed pending stabilization of SparkSqlDialect emission for the join+aggregate form.
