1. update std to [email protected] and esbuild to [email protected]
2. remove esbuild wasm code and unit tests
3. A sub-bundle feature for module-imported with name and directory customized support, using comment before import // \!bundle=off|module|[/dir/][name]
4. fix test cases issues

// !bundle=module
import { hello } from "world.ts";
