Move Wi-Fi calling related feature into it.
Which simplifies the ImsMmTelRepository, so we can put more
ImsMmTelManager related features into ImsMmTelRepository in the future
cl.

Move the following to background thread to avoid block main thread,
- MobileNetworkUtils.isWifiCallingEnabled(mContext, mSubId, null)
- MobileNetworkUtils.buildPhoneAccountConfigureIntent()
- getSummaryForWfcMode()
- Call State
Since WifiCallingPreferenceController no longer calculate availability
in getAvailabilityStatus(), also update the
CallingPreferenceCategoryController accordingly.
Also introduce ImsMmTelRepository for split business logic for easy
testing.
