Do not set Notetaking shortcut to default if Stylus is not detected

The current implementation set Notetaking shortcut as default in the keyguard for any device that contains Note Role - besides being able to manually add to the lock-screen, we should only set it as default whew a Stylus is detected (i.e., touch the screen or has been paired).

Testing instructions:
1. The device supports Note Task (i.e., tablets).
2. A Stylus.
3. Note Task feature flag is enabled: `adb shell cmd statusbar flag 1900 on`
4. Quick Affordance flag is enabled: `adb shell cmd statusbar flag 216 on`
5. Quick Affordance new UI flag is enabled: `adb shell cmd statusbar flag 222 on`
