Its value is always the same as the child.output. Remove it from the class `Window`. Removal can simplify the codes in Analyzer and Optimizer. \r\n\r\nThis PR is based on the discussion started by @cloud-fan in a separate PR: \r\nhttps://github.com/apache/spark/pull/5604#discussion_r55140466\r\n\r\nThis PR also eliminates useless `Window`. \r\n\r\n@cloud-fan @yhuai \r\n\r\n#### How was this patch tested?\r\n\r\nExisting test cases cover it.
