Add notification for onInferenceServiceDisconnected

When Inference is killed either during OOM by LMKD or if service crashes. System-Server receieved a onServiceDisconnected callback. This callback should be used to propogate notifyInferenceServiceDisconnected to AICore non-isolated service - but this is currently missing.


Bug: 366029924
Test: verified locally, callback is invoked on inference process crash
Flag: EXEMPT bugfix
