Add APIs to update and listen to deviceId changes in Context

- Adds a updateDeviceId @hide API that can be used by the system
  to update the device association of a Context that is not
  explicitly created as a Device Context.
- Adds a listener that would be notified whenever the deviceId
  of the Context has changed.
- Adds an isDeviceContext() API that can be used to determine
  if the device ID returned by getDeviceId() is reliable for
  this Context instance.

These APIs will enable implicit deviceId association for Contexts
that are not Device Contexts.
