fix(plsql): add MAXSIZE option to STORAGE clause grammar

[h3n4l]

Summary

• Added MAXSIZE (UNLIMITED | size_clause) to the Oracle storage_clause grammar rule
• Added test case from BYT-9088 reproducing the exact DDL with ROW STORE COMPRESS ADVANCED and STORAGE(... MAXSIZE UNLIMITED ...)

Test plan

• make build — parser regenerated successfully
• make test — all 343+ test cases pass including the new test case

This change adds a large, production-like DDL statement into plsql/examples/create_table.sql. If this is intended primarily as a regression fixture for BYT-9088, consider moving it into a smaller, dedicated example/fixture file (e.g., plsql/examples/byt-9088.sql or a test-fixtures directory if one exists) to keep create_table.sql from growing into an unmanageable catch-all corpus.
