ENG-7202:
- Copy things that were added to canonicalddl/fullDDL.sql and
  not to fullddlfeatures/fullDDL.sql to fullddlfeatures/fullDDL.sql.
- Make final changes to consolidate "fullDDL" into one file:
-- cosmetic things for canonically generated diff matching
-- comment out IMPORT CLASS and resulting procedure creation
-- comment out groovy stored proc until sqlcmd handles groovy escape
   sigil
-- delete the redundant file and point the canonical test at the one,
   true fullDDL.sql
