/**

 *
 * @param props Prop objects to merge.
 * @returns Merged props.
 *
 * @example
 * ```ts
 * mergeProps({ class: 'p-button', onClick: onOuter }, { class: 'p-button-sm', onClick: onInner });
 * // { class: 'p-button p-button-sm', onClick: (...args) => { onOuter(...args); onInner(...args); } }
