Support Dynamic ImsService Querying
1) Provide a "default" impl for MmTelFeature
instead of returning null.
2) Introduce a FeatureSlotPair, which maps a SIM
slot ID to a ImsFeature. This allows the ImsService
to provide which features it supports for multi-SIM
phones.
3) Pipe through ImsResolver state to help prevent IMS
operation when the ImsResolver is in the process of
figuring out feature capabilities.
Test: Telephony ImsService test app, telephony unit tests
