Clone data segments when specified with load args (#3463) 
Follow-up on https://github.com/bytecodealliance/wasm-micro-runtime/pull/3389, specifically: https://github.com/bytecodealliance/wasm-micro-runtime/pull/3389#discussion_r1600872451

If we want to free the wasm binary buffer early, we need to clone the data segments into the module.
That's because, in case of [passive data segments](https://webassembly.github.io/threads/core/syntax/modules.html#syntax-data),
they can be referred during wasm execution.
