Why remove the <Icon/> component?🙏

[ZenkieBear]

English:
While ant design decided use SVG component instead of font icon, the Icon is used for some business!
It provide a way to render icon through the icon tag.
We have a business used this component like that.

We should keep Icon, but we can replace the implementation of icons.

Now the Icon throw an warning:

Warning: [antd-compatible: Icon] The legacy component has been deprecated, and ant design 4.0 now released! Please follow https://ant.design/components/icon to upgrade.

中文：
即便 ant design 决定使用 SVG 组件来代替字体图标，Icon 依然被使用在某些业务上！
它提供了一种方式通过图标标签（名称字符串）来渲染图标。
我们正有一个业务如此。

我们可以替换图标的实现方式，但是应该保留Icon组件。

现在我们的Icon会在控制台打印一条警告：

Warning: [antd-compatible: Icon] The legacy component has been deprecated, and ant design 4.0 now released! Please follow https://ant.design/components/icon to upgrade.

English:
I don't know when it will be removed from antd, but it couldn't be found in 4.0's and 5.0's document.
If it removed, our team have to implement an icon-provider component which is familiar to Icon, that's redundant and unnecessary!

中文：
我不知道它什么时候会从 antd 中移除，但它已经无法从 4.0 和 5.0 的文档中找到了。
如果它被移除，我们的团队必须重新实现一个和 Icon 类似的 图标提供器 ，这是冗余而且没有必要的！

In Font Awesome，there is a same provider named FontAwesomeIcon: https://fontawesome.com/docs/web/use-with/react/add-icons. And they implemented SVG icons.

在 Font Awesome，他们也有一个类似的提供器名为 FontAwesomeIcon，而且他们也实现了 SVG 图标。
