…a expression is nondeterministic or not (apache#39801) ## Proposed changes In apache#36111, we add `isDeterministic` method in class `ExpressionTrait` to identify the expression is deterministic or not. But `unix_timestamp` doesn't extend Nondeterministic, but it is not deterministic when it's children is empty. and is not deterministic when children is not empty. If we use` instanceOf Nondeterministic `to indentify if expression is is not deterministic, that is confused. So we do something as fllowing: 1. Remove Nondeterministic class, and use `isDeterministic` to indentify it's deterministic. 2. Add `containsNondeterministic` method in `ExpressionTrait` to identify it contains nondeterministic expression or not. 3. `isDeterministic` only identify current expression is deterministic or not. would identify if contains nondeterministic or not
