This is the initial support for npm and node specifiers in `deno compile`. The npm packages are included in the binary and read from it via a virtual file system. This also supports the `--node-modules-dir` flag, dependencies specified in a package.json, and npm binary commands (ex. `deno compile --unstable npm:cowsay`) Closes #16632
