/**
 * `hostBinding` takes a `hostPropertyName` to attach a data property, a class, a style or an attribute (as `@HostBinding` would) to the host.
 * The udpate is applied based on the update of the provided signal (writable or not).
 *
 * @param {Required<HostBinding>['hostPropertyName']} hostPropertyName - the same property that is bound to a data property, a class, a style or an attribute as `@HostBinding`.
 * @param {Signal | WritableSignal} signal - the signal on which to react to changes to update the host, and the one that will be returned as it is
 * @returns {Signal | WritableSignal}
 *
 * @example
 * ```ts
 * export class MyComponent {
 *  readonly background = hostBinding('style.background', signal('blue'));
 *
 *  constructor() {
 *    setTimeout(() => this.background.set('red'), 3000);
 *  }
 * }
 * ```
