Harshil Shah bce6ece5f6 Add symlinks under node_modules as part of projectRoots
Summary:
Support symlinks under `node_modules` for all local-cli commands. PR https://github.com/facebook/react-native/pull/9009 only adds symlink support to the packager.

But other cli commands like `react-native bundle` creates its own instance of packager that doesn't have symlinks as part of its project roots, which results in the bundler breaking since it cannot find modules that you have symlinked.

This change ensures all `local-cli` commands add symlinks to its project roots.

Test plan (required)

1.  Create a symlink in node_modules (for instance use npm/yarn link)
2. Run `react-native bundle`.
Closes https://github.com/facebook/react-native/pull/11810
