jni_generator: Refactor/clean up tests

- Move golden/javap files to jni_generator/golden/
- Make method capitalization more consistent with jni_generator py files
- Split proxy native tests to a different test suite
- Decouple utility functions from TestGenerator into a base test class
- Fix bug where tests would fail if ran from a different directory
- Adds tests for enable/disable/require mock flags
