    SystemUI: Enhancement for volte icon

    SystemUI uses callback to get ims capabilities and then check whether
    ims is registered. If low layer updates ims registered later than
    capabilities, SystemUI wil miss the ims registered value.

    In this case, SystemUI monitors both ims capabilities and registered.

    SystemUI: Fix HD icon missing

    When SIM is changed to OOS, IMS Connection is closed and
    all the active callbacks are removed, so SystemUI can not
    get the IMS registration messages after that.

    Replace ImsRegistrationImplBase.Callback with
    ImsFeature.CapabilityCallback,
    Register the callback when IMS connection is available.

    Adapt to IMS registration changes.

    The upstream change
    https://keystone-qcom.googlesource.com/platform/frameworks/base/+/941c0a5cfd5cdfe8a19c2928486fab9efa489ada


    modified the class to use when registering with ImsManager from
    android.telephony.ims.stub.ImsRegistrationImplBase.Callback to
    android.telephony.ims.ImsMmTelManager.RegistrationCallback. This keystone
    change adapts a Qualcomm addition to the upstream change.

    SystemUI: Fix volte icon doesn't update in real time

    SystemUI will clean and reinitialize the subscripiton state
    when active subscripitons are chagned, but telephony doesn't
    report the ims registration state if it is not chagned.

    When two sims are both registered on ims, hotswap sim1.
    In this case, the volte icon of sim2 will not be updated in time

    Now we query the ims registration state first when reinitialize
    the subscripiton state; we also query the ims registration state
    when receiveing ImsRegistrationImplBase.Callback
