If the PR you submit will have an impact on performance, please benchmark it first and provide the benchmark result here. --> ## What does this PR do? The `MetaString` class is introduced to handle Unicode encoding and decoding for strings used in the code generation process for `Type.Object`. This ensures that strings are properly encoded and decoded during storage and transmission. - **Encoding**: Converts Unicode strings into an encoded format. - **Decoding**: Converts encoded strings back to their original Unicode format. The `MetaString` class is used in `object.ts` to handle string encoding and decoding when generating code for `Type.Object`. ## Related issues Is there any related issue?

Implement the object metadata compression protocol: type metadata encoding and parsing.
Describe the solution you'd like
#1556 can be taken as an example to type meta encoding.
Note that #1556 is only for type meta in java serialization, not for type encoding in java for xlang serialization
