Optimize ByteCodeTranslator by parallelizing class parsing and code generation.

* Parallelized file processing in `ByteCodeTranslator.execute` using `ExecutorService`.
* Parallelized dependency updates and file writing in `Parser.writeOutput`.
* Ensured thread safety in `Parser`, `ByteCodeClass`, and `BytecodeMethod` by using `ReentrantReadWriteLock` for shared resources (`classes`, `constantPool`, `arrayTypes`, `writableFields`, `virtualMethodsInvoked`) and synchronized methods where appropriate.
* Fixed brittle test `BytecodeInstructionIntegrationTest` that relied on anonymous inner class index.
