<FormItem>表单校验的rules总是会以formItem的rules替代form的rules，然而更期望是合并的rules

[hcg1023]

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

What problem does this feature solve?

期望在form定义rules之后，在formItem的rules会与form的rules合并，而并非直接使form的rules失效，导致form定义的rules无效

What does the proposed API look like?

form或者formItem可以有一个mergeRules的props，用于将formItem与form的rules合并，而非替换

可以考虑添加合并策略的参数配置项，默认给出何必策略，不满足时，配置项配置为函数，自己实现何必策略。类似Vue的options何必策略
