Push flags from top-level TypedValue into ComplexColor changing configs

Previously a ComplexColor that was defined within varying configs would
not push the flags into its changing configs, so it wouldn't get reloaded.

This implementation follows the Drawable implementation, where the base
changing configs are stored in the superclass.
