Add TypeName and DefineStmt args context to Integer transformation

- Handle TypeName arrayBounds context: empty Integer objects transform to ival: -1
- Handle DefineStmt args context: empty Integer objects transform to ival: -1
- Improved test pass rate from 181 to 194 passing tests (13 test improvement)
- Addresses both over-transformation and under-transformation issues
- Based on alter_table test failure patterns and v14-to-v15 transformer patterns
