test(compiler): verify opcode build state in incremental compilation

- Added assertion to check opcodeBuildChecked property is false
- Used reflection to access parent class properties when needed
- Removed anonymousOpcode configuration from build parameters
- Ensured proper state verification for compiler fingerprint tests
