问题背景

解决方案

修改 rc-picker 默认格式化优先使用 locale 中的 format：

• weekFormat
• monthFormat
• quarterFormat
• yearFormat
• dateTimeFormat
• dateFormat

从问题背景可以得知，这原本应该属于 antd3 的 feature，但是在升级为 4 的时候丢失了这个功能，导致开发者无法通过 CP 组件全局设置 antd 组件的格式化。该 PR 修复问题时，不得不改变原有的 src/locale/en_US.ts 文件来满足当前的测试用例。为了尽可能缩小影响范围，但是可能还是存在 BreakChange，仅管 antd4 已经没有用到 locale 中的 format，但如果有开发者二次开发引用到了 locale 文件，这无法避免破坏性变动了。以上
