Currently there is a limitation where ResourcesLoaders cannot be used on Resources object not created through ResourcesManager. This change creates an update handler for Resources objects that are not registered with ResourcesManager. The handler changes the loaders on the asset manager owned by the Resources instance. Bug: 151666644 Test: atest ResourceLoaderValuesTest Change-Id: I5a89f686386bdb088dc964014e7becc0c2b4770f
