[SPARK-11053] Remove use of KVIterator in SortBasedAggregationIterator
SortBasedAggregationIterator uses a KVIterator interface in order to process input rows as key-value pairs, but this use of KVIterator is unnecessary, slightly complicates the code, and might hurt performance. This patch refactors this code to remove the use of this extra layer of iterator wrapping and simplifies other parts of the code in the process.

Closes #9066 from JoshRosen/sort-iterator-cleanup.
