Description

What problem does this feature solve?

Validator添加自定义规则时候：

Validator.addRule('odd', (val, config, type) => !config || Number(val) % 2 === 1)
Validator.addMessage('odd', 'Please input odd.')

显得比较蛋疼，最好能链式调用

Validator.addRule('odd', (val, config, type) => !config || Number(val) % 2 === 1)
.addMessage('odd', 'Please input odd.')

显得比较优雅

Research direction
The issue requests chaining support for Validator.addRule and Validator.addMessage methods. The implementation likely involves modifying these methods to return `this` for chaining. Look at the Validator source in the cube ui repository (e.g., src/common/validator.js). Ensure backward compatibility and update documentation if needed.
