Support Node.js args to built-script executor (#92)

## Motivation for the change, related issues

When running Playground CLI and php-wasm CLI with the built-script
executor, I've wanted to add extra Node.js flags like
`--experimental-wasm-jspi`.

Prior to this PR, the only way was to hack the executor.ts file, but
these changes show up in `git status` and are easy to misplace and lose
when switching between branches and pushing and popping from the stash.

## Implementation details

This PR adds a `nodeArg` option to our custom `built-script` executor.
It is an array and can be specified multiple times to add multiple args.

## Testing Instructions (or ideally a Blueprint)

The built-script executor is only used by Playground CLI and php-wasm
CLI. Let's test both.

Run the following command:
```
npx nx start php-wasm-cli --nodeArg='--cpu-prof' --nodeArg='--trace-promises' -r 'phpinfo();'
```

- Confirm you see promise tracing in the output
- Confirm the command created a file ending in `.cpuprofile`

Run `npx nx start playground-cli server` to confirm it is still working.
