[FEATURE] Support multi-language access for native structs

[Officeyutong]

Support generating modules that can provide ability to access structs passed from native programs (e.g kernel) using BTF for golang and rust.

• Generating a WASM module that provide functions which can access a native struct using base pointer, struct type name, field name. Information can be obtained from a BTF file and then hard-coded in the generated WASM module for acceleration.

This could be done in https://github.com/eunomia-bpf/c-struct-bindgen
