Previously, module splitting with JSPI required a special built-in function `__load_secondary_module` and wasm-split setting to coordinate the loading of the secondary module. This change updates the `splitModuleProxyHandler` to support JSPI by wrapping the generated placeholder functions in `WebAssembly.Suspending`. The placeholder will then automatically load the secondary module asynchronously. A standalone `save_profile_data.js` script is extracted from existing tests for reuse, and a new test `test_split_module_embind_jspi` is added to ensure module splitting functions correctly alongside embind and JSPI.

For some more context: The old version of JSPI required changes to wasm so this new approach wasn't possible. |
