Camera: Pass metadataGetter from CameraDeviceClient

As part of HIDL->AIDL conversion, the metadataGetter has been changed
to use the mPhysicalCameraCharacteristics within the DeviceInfo3. But
for the case where a physical camera is a public available camera Id,
the lookup will fail.

Revert back to previous logic where the metadataGetter is based on
Camera3Device, which has knowledge of all physical camera's
characteristics.
