- Run the embedder entry point directly through runEmbedderEntryPoint(), instead of going through another JS -> C++ trip through the function returned by getEmbedderEntryFunction() - For --build-snapshot, read the snapshot script code directly in C++ and pass it to SnapshotBuilder::Generate(), this makes the entry point more explicit instead of hiding it in JS land, and also makes it possible to invoke SnapshotBuilder::Generate() internally to create a custom snapshot. - Previously we used process.execPath for the embedder to create __filename and __dirname in the snapshot builder script while using process.argv[1] for --build-snapshot (where it's always set) which results in inconsistencies. We now require the embedder to also set args[1] when creating the Environment if they intend to run snapshot scripts with a context that contains __filename and __dirname, which would be derived from args[1]. If they prefer not to include build-time paths in the snapshot, we now provide node::GetAnonymousMainPath() as an alternative.
