Faces 4.0: remove deprecated ResourceResolver

[BalusC]

ResourceResolver was deprecated since 2.2:

 * <span class="changed_deleted_2_2">Deprecated as of Jakarta Server Faces 2.2. The same functionality is more correctly
 * provided by {@link jakarta.faces.application.ResourceHandler}.</span> Provide a hook to decorate or override the way
 * that Facelets loads template files. A default implementation must be provided that satisfies the requirements for
 * loading templates as in Pre-Jakarta Server Faces 2.0 Facelets.

It's time to remove it.

For a real world example of migration from ResourceResolver to ResourceHandler, take this OmniFaces commit as an example: omnifaces/omnifaces@65d6c3a#diff-2fcedbdaa1d6c98f1597f920fff6e3611c18e9320c2201f8ae4c174d7e3656e1

Summary, this usage of ResourceResolver

public class YourResourceResolver extends ResourceResolver {

	private final ResourceResolver wrapped;

	public YourResourceResolver(ResourceResolver wrapped) {
		this.wrapped = wrapped;
	}

	@Override
	public URL resolveUrl(String path) {
                String actualPath = doYourMagicWith(path);
		URL resource = wrapped.resolveUrl(actualPath);
		return resource;
	}

}

can be rewritten to this usage of ResourceHandler

public class YourResourceHandler extends ResourceHandlerWrapper {

	public YourResourceHandler(ResourceHandler wrapped) {
		super(wrapped);
	}

	@Override
	public ViewResource createViewResource(FacesContext context, String path) {
                String actualPath = doYourMagicWith(path);
		ViewResource resource = super.createViewResource(context, actualPath);
		return resource;
	}

}
