This PR resolves the following issue #28868 I tried to apply the practices used in prior deprecation (ex : PropertyPlaceholderConfigurer, FailureCallback) which are :
- Deprecate all classes fully related to theming
- Update javadoc with
@deprecated as of 6.0, with no direct replacement
- Remove imports in other classes
- Deprecate methods and classes related to theming in other classes
- Update javadoc in other classes with
Theme support is deprecated as of 6.0
- Suppress the deprecation warnings in test classes
