Allow legacy mode voicemail notification to show in FBE

Legacy mode is when the carrier notifies the device of incoming voicemails with visual voicemail SMS, but the device shows a legacy voicemail notification and will not access the voicemail server. This is used by certain carriers to pretend VVM is deactivated, or under FBE because the server access credentials is encrypted.

Previously the VVM activation state is made available in FBE, so all legacy voicemail notifications will be blocked, including legacy mode.

In this CL, legacy mode will send an additional flag so it will not be blocked by the VVM activated state.
