fix: next build lagging

[zombieJ]

NextJS will build long time when code has .concat:

// More `.concat` has, more lag of it
'a'.concat(b, 'c').concat(d, 'e')...

Since it's build from babel, we can not destruct this without configuration. Modify with list join instead.

我记得以前是不是编译成 '+' 来减小包体积来着？

那个是 antd 侧的，rc 侧还是保持兼容态。
