AOSP API support for Sip Dialog status callback

All active RCS services must be maintained from WiFi to RAN or from RAN to WiFi.
According to the carrier specification, QNS applied this API because it needs to know if the MSRP service is activated during handover.

Test: atest SipSessionTrackerTest
Test: cts SipDelegateManagerTest

Bug: b/244429207
