[ARCTIC-459][FLINK] Fix the missing of the required fields after project pushdown

[zstraw]

FIX #459

Why are the changes needed?

Project pushdown may lead to the missing of primary key, partition key. ShuffleHelper may lose the required info, and produce NPE.

This hotfix tends to read the required fields appended after the projected fields in the order of 'projected fields', 'primary keys', 'partition keys'. And send the rowData with additional fields to downstream.
