Description

Adds two useful rules to the eslint config for no-restricted-imports:

1. We include react-native-safe-area-view and should always use the SafeAreaView from that library instead of from react-native
2. We have our own custom Text, TextField (TextInput), and Button components. Add rules to disallow these from react-native to ensure developers are using the components that ship with ignite and not importing from react-native.

Checklist

• I have manually tested this, including by generating a new app locally (see docs).
