- Add support for --build-snapshot-config which allows passing snapshot configurations via a JSON configuration file. - Add support for node::SnapshotConfig in the embedder API The initial configurable options are: - "builder" (SnapshotConfig::builder_script_path): path to the builder script. - "withoutCodeCache" (SnapshotFlags::kWithoutCodeCache): disable code cache generation.
