 * 获取关键帧的所有值

 * @returns {Array<Keyframe>}
 * @since 0.1.0
 * @category Soil
 * @see {@linkcode setKeyframeValues}
 * @example
 *
 * ```ts
 * const activeComp = _.getActiveComp();
 * if (_.isCompItem(activeComp)) {
 *     const selectedProperty = activeComp.selectedProperties[0];
 *     if (_.canSetPropertyValue(selectedProperty)) {
 *         // 注意：keyLabel 方法在 Ae 22.6 中添加。
 *         const redKeys = _.getKeyframeValues(selectedProperty, function (property, keyIndex) {
 *             return property.keyLabel(keyIndex) === 1;
 *         });
 *         _.log(redKeys);
 *     }
 * }
 * // 结果：桌面 json 日志会记录所有被过滤的红色关键帧的值。
