/**
 * Class decorator that configures reactive ARIA element-reference forwarding
 * from the host web component to inner shadow DOM elements.
 *
 * Both `aria-*` and `gds-aria-*` attributes are observed. When either changes,
 * the space-separated IDs are resolved to elements via `getElementById` and
 * forwarded to the configured target element using the ARIAMixin element-reference
 * property (e.g., `ariaLabelledByElements`).
 *
 * The `aria*Elements` properties are also intercepted on the host, so programmatic
 * setting (e.g., `el.ariaLabelledByElements = [label]`) is forwarded as well.
 *
 * Config values are CSS selector strings resolved against the component's shadowRoot.
 *
 * @example
 * ```ts
 * @ariaForwarding({
 *   labelledBy: 'input',
 *   describedBy: 'input',
 *   activeDescendant: '[role="listbox"]',
 * })
 * @gdsCustomElement('gds-input')
 * class GdsInput extends GdsFormControlElement { ... }
 * ```
