AuthService registerFaceSensor for hidl should only focus on face hidlConfigStrings

registerFaceSensor will register for FaceUnclok HIDL and AIDL,
and in the begining setup FaceSensorConfigurations, it will mistake parser all the hidlConfigStrings.

And that will cause some buggy if device implement with fingerprint HIDL and FaceUnlock AIDL,
the FaceUnlock AIDL will be treated as HIDL.

Bug: 363894516
Test: Manual see the log of AuthService when booting.
