Add schema dumps and expected outputs for decimal migration_diff test

- Created schema-dump-test_comparisons_mysql.lock and pgsql.lock with DECIMAL(8,2)
- Modified setup migrations to CREATE table instead of CHANGE column
- Added expected output files in mysql/ and pgsql/ subdirectories with CHANGE column
- This allows the diff command to compare DB (10,2) vs dump (8,2) and generate changeColumn migration
