[SPARK-24979][SQL] add AnalysisHelper#resolveOperatorsUp

[cloud-fan]

What changes were proposed in this pull request?

This is a followup of #21822

Similar to TreeNode, AnalysisHelper should also provide 3 versions of transformations: resolveOperatorsUp, resolveOperatorsDown and resolveOperators.

This PR adds the missing resolveOperatorsUp, and also fixes some code style which is missed in #21822

How was this patch tested?

existing tests.

@cloud-fan, thanks! I am a bot who has found some folks who might be able to help with the review:@gatorsmile, @yhuai and @rxin

Do we really need this? It's almost always the case for resolution that you'd want to do bottom up, so I thought Michael's original design to just call it resolveOperators make a lot of sense.

[cloud-fan]

@rxin there are different patterns

1. only match a node if its children are resolved. This is the most common pattern and we should transform up.
2. match a specific node without checking if children are resolved. This pattern doesn't care about transform direction.
3. match a group of nodes, like case Filter(cond, Aggregate(...)). This pattern needs transform down.

It's a little confusing to only have resolveOperators and resolveOperatorsDown, especially we change some rules from transform to resolveOperatorsDown. It took me a while to think about why we specify the down direction for these rules, then I realized TreeNode.transform calls transformDown and we want to keep the previous transform direction.
