[PwdCheckAndroid] Serialize CompromisedCredential for editing

By making CompromisedCredential implement Parcelable and provide a
static CREATOR, it can be serialized and used in Bundles. This enables
to pass it as extra when:
 * Saving the instance state if an activity is recreated
 * Starting fragments that need a compromised credential as extra
