HarmonyOS capi阴影样式（NODE_CUSTOM_SHADOW）设置不生效

参考示例如下：

unsigned int colors[] = {0xFFFF0000, 0xFF00FF00, 0xFF0000FF};
float stops[] = {-0.2, 0.5, 1.0};
ArkUI_ColorStop colorStop = {colors, stops, 3};
ArkUI_ColorStop *ptr = &colorStop;
ArkUI_NumberValue valueColor[] = {{.f32 = 60}, {.i32 = 0}, {.i32 = true}};
ArkUI_AttributeItem itemColor = {valueColor, sizeof(valueColor) / sizeof(ArkUI_NumberValue),
                                 .object = reinterpret_cast<void *>(ptr)};
nodeAPI->setAttribute(columnTmp, NODE_LINEAR_GRADIENT, &itemColor);
ArkUI_NumberValue valueShadow[] = {
    {.f32 = 20.0},       {.i32 = 0}, {.f32 = 10.0}, {.f32 = 10.0}, {.i32 = ARKUI_SHADOW_TYPE_COLOR},
    {.u32 = 0xffffff00}, {.u32 = 0}};
ArkUI_AttributeItem testShadow = {valueShadow, sizeof(valueShadow) / sizeof(ArkUI_NumberValue)};
