[SPARK-13544] [SQL] Rewrite/Propagate Constraints for Aliases in Aggregate 
and Windows

 What changes were proposed in this pull request?

After analysis by Analyzer, three operators could have alias. They are 
`Project`, `Aggregate` and `Window`. So far, we only rewrite and propagate 
constraints if `Alias` is defined in `Project`. This PR is to resolve this 
issue in `Aggregate` and `Window`.

 How was this patch tested?

Added a test case for `Aggregate` in `ConstraintPropagationSuite`. We do 
not have a DSL for `Window`. It is a little bit tedious to add such a similar 
case for `Windows`. Could we skip it? : )
