Small refactor on WASMModuleInstance and fix Go/Python language bindings (#3227)

- Merge unused field `used_to_be_wasi_ctx` in `AOTModuleInstance` into `reserved` area
- Add field `memory_lock` in `WASMMemoryInstance` for future refactor
- Go binding: fix type error
    https://github.com/bytecodealliance/wasm-micro-runtime/issues/3220
- Python binding:
    type annotation uses the union operator "|", which requires Python version >=3.10
