[TRAFODION-1423] Indexes on trafodion should be created in aligned row
format by default
A new CQD TRAF_INDEX_ALIGNED_ROW_FORMAT is set to ON by default.
The indexes are created in the aligned row format when this
CQD is set to ON and the table has no serialized column.

[TRAODION-1423] Indexes in the aligned row format more changes
Fixed the comment in exp/ExpAlignedFormat.h to reflect
the aligned row format layout correctly.
Made distinction between the table having serialized
columns and serialized encoded columns in the NATable structure.
Indexes are not created in aligned format if the table had
serialized column.

[TRAFODION-1423] - Indexes in aligned row format
Made changes as per the reviewer comments. Refactored the
the aligned row format to be part of NAFileSet. However,
the CQD TRAF_INDEX_ALIGNED_ROW_FORMAT is changed to 'OFF'
by default.
