*** Original commit *** Remove `@Nullable` from `MediaSource.Factory` setters The null-behaviour of these methods creates a minimization footgun, because **any** call to these setters will prevent R8 from removing the default implementation (even if it's never used by the app) - this is because R8 can't tell the default implementation is only used if the parameter is `null`. ****** PiperOrigin-RevId: 450410833
