Return back-up slices for unavailable settings

When an inline slice is requested, and the setting is unavailable,
we should present more useful information to the user. This CL handles:
- Unsupported: return intent slice to Settings home page
- Disabled for user: intent to the setting page
- Unknown reason: intent to setting page
- Disabled dependency: Create intent-based Slice rather
than the requested inline slice.
