能不能优化一下Y轴平移

- [ ] I have searched the [issues](https://github.com/antvis/f2/issues) of this repository and believe that this is not a duplicate.

### What problem does this feature solve?
层叠条形图，肯定会有Y轴平移的需求。但是scrollBar: { mode: 'y' }：
1. 样式很怪
2. 只能移动水平方向移动

### What does the proposed API look like?
期待可以思考的周全一些

Start by reproducing the stacked bar chart case described in issue #1181 and inspect the existing scrollBar: { mode: 'y' } behavior. Review how the current API handles styling and movement direction; done should mean that Y-axis panning works as expected with a sensible scrollbar style and a clearly defined API.
