Add Keyguard Shortcut for Note Task

Allow a user to manually set a Note Task shortcut in the Keyguard screen using the new Quick Affordance UI. The shortcut should only be available when:
1. The device supports Note Task (i.e., tablets).
2. Note Task feature flag is enabled: `adb shell cmd statusbar flag 1900 on`
3. Quick Affordance flag is enabled: `adb shell cmd statusbar flag 216 on`
4. Quick Affordance new UI flag is enabled: `adb shell cmd statusbar flag 222 on`

Later, we will add it as a default on the Keyguard to any device running `TitanSysuiConfigOverlay` if and only if a Stylus is detected (i.e., first usage).
