Icon 自定义 font 图标 extraCommonProps未生效

[okbeng03]

• I have searched the issues of this repository and believe that this is not a duplicate.

What problem does this feature solve?

文档中说明通过 extraCommonProps 可以设置额外属性，类似className，不过看了下源码，并没有使用到这个属性，是不是漏掉了

What does the proposed API look like?

支持 extraCommonProps 设置额外属性
