Unified vite/webpack analyze product

[nonzzz]

I notice in vite mode. umi is using rollup-plugin-visualizer to display the bundle analyzer result. But isn't same with webpack version. AFAIK i think the rollup-plugin-visualizer squarifed treemap isn't convenient to operate. So i made a new plugin vite-bundle-analyzer

Why new plugin?

• vite-bundle-analyzer is focus on the behavior with webpack version and has a very small bundle size and faster loading bundle result speed.

And it also has a certain number of users. Here are the users list.

@xierenyuan 可以看下这个插件如何，如果更好有帮助的话，可以考虑把 rollup-plugin-visualizer 给替换掉，这个应该只是小插件，替换了没啥影响。

另外我理解用户可以自己用 modifyViteConfig 来添加这个插件手动使用。
