[identity] Remove device data on device list update

Summary:
Resolves ENG-7897.
We should not rely on secondary device removing CSAT and keys on its own. This diff adds a failover mechanism,
that invalidates CSAT and removes device keys when primary device updates the device list, just in case
secondary device failed to remove it before logging out.

These calls are idempotent - they're no-op when CSAT or keys have been already removed.

Depends on D12225

Test Plan:
Secondary logout flow:

• Commented-out the LogOutSecondaryDevice RPC call
• Confirmed that device keys were removed from DDB
