There was a problem hiding this comment.
Drive-by: fixed this since it seems out of touch with other APIs below.
This uses the new StartExecutionCallbackWithModule embedder API to support ESM entrypoint in SEA via a new configuration field `"mainFormat"`. The behavior currently aligns with the embedder API and is mostly in sync with the CommonJS entry point behavior, except that support for code caching and snapshot is left for follow-ups.
