Add support for deprecated component type aliases to extensions, following the implementation started in #14349 The new `xextension.WithDeprecatedTypeAlias` factory option allows extension authors to register deprecated type aliases using: ```go xextension.NewFactory( newType, createDefaultConfig, createExtension, component.StabilityLevelAlpha, xextension.WithDeprecatedTypeAlias(oldType), )
