同步vc-util/Dom/dynamicCSS

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

What problem does this feature solve?

从"rc-util/lib/Dom/dynamicCSS"同步最新的代码以支持"cssinjs"的"priority"

What does the proposed API look like?

最新的"rc-util/lib/Dom/dynamicCSS"补充了"APPEND_PRIORITY",并调整相关插入逻辑.

本地patch之后,"useStyleRegister"的第一个参数的"order"才能正确生效.

该框架版本不更新了吗？跑路了？一年多了，官方react都快6.0了
