Add experimental support for loading snapshots in the embedder API by adding a public opaque wrapper for our `SnapshotData` struct and allowing embedders to pass it to the relevant setup functions. Where applicable, use these helpers to deduplicate existing code in Node.js’s startup path. This has shown a 40 % startup performance increase for a real-world application, even with the somewhat limited current support for built-in modules. The documentation includes a note about no guarantees for API or ABI stability for this feature while it is experimental.
