Add `extension.BundledModule` to Wrap `extension.Module` with Bundled Program Logic

[zhenyan-zhang-meta]

Context

This issue is a step of #9638 and a sequel of #10364.

In #9638, we want to have extension.Module as the single source of implementation in pybindings, which means that pybindings.PyModule should use extension.Module rather than its own pybindings.Module.

The issue is that pybindings.PyModule is dependent on the method getter from pybindings.Module, which extension.Module do not have. Since we don't want to expose method getter in extension.Module, we have to protect the getter, wrap the functions that is dependent on it and use the protected getter there, ultimately decouple pybindings from a method getter.

Proposal

Now that we have a protected method_ to use, we can introduce a extension.BundledModule, a child class inheriting extension.Module which wraps up bundled program logic that is dependent on the method getter.

class BundledModule : public Module {
   
  // Load a specific method with the input value at the given `testset_idx` from the bundle to the method.
  ET_NODISCARD runtime::Error load_bundled_input(
      const std::string& method_name,
      const size_t testset_idx);

   // Verify the output of a specific method with the expected output from the program bundle at the given `testset_idx`.
   ET_NODISCARD inline runtime::Result<bool> verify_output_with_bundled(const std::string& method_name, const size_t bundled_output_index, std::vector<runtime::Evalue>> method_output; other_comparsion_configs);
}
