Fix location settings bug on non-GPS devices

The old location_mode API hardcoded gps and network location provider when it enables/disables location, without checking whether the providers exist on device.
It causes bugs when used together with the new
LocationManager.setLocationEnabled() APIs.

This fix modified LocationManager.setLocationEnabled() API when user
tries to disable location on device. Besides turning off the providers
from LocationManager.getAllProviders(), it also turns off GPS and
network provider explicitly.

To reduce times of binding to the service and chance of race condition, we also
modified SettingsProvider.updateLocationProvidersAllowedLocked() to
accept a string param with multiple location providers to be
enabled or disalbed at the same time.
