bootstrap: optimize modules loaded in the built-in snapshot

Preload essential modules and lazy-load non-essential ones.
After this patch, all modules listed by running this snippet:

```
const list = process.moduleLoadList.join('\n');
require('fs').writeSync(1, list, 'utf-8');
```

(which is roughly the same list as the one in
test-bootstrap-module.js for the main thread)
are loaded from the snapshot so no additional compilation cost
is incurred.
