ElevationThemeData class

定义后代小部件的默认elevation

elevation是两个表面之间沿 z 轴的相对距离。

后代小部件使用 SpacingTheme.of(context) 获取当前的 ElevationThemeData 对象。 ElevationThemeData 的实例可以使用 ElevationThemeData.copyWith 进行自定义。

新增属性时需同时更新ElevationThemeData默认构造方法、copyWith方法、lerp方法

配置参考https://m3.material.io/styles/elevation/overview
