支持获取多个值的query参数

(Optional) More detail description for this PR(en: English/zh: Chinese).

en:
ctx.Query cannot get multiple values of a from a=1&a=2&b=1.
QueryArray is provided in gin to get multiple values, but rfc3986 does not define the implementation of the server, and many frameworks are inconsistent when parsing repeated queries , some only use the first or last occurrence.
So I'm not sure it needs to be implemented in RequestContext, but I hope there is still a way to get it.

 ctx.QueryArgs().PeekMulti("a")

zh(optional):
ctx.Query 无法从 a=1&a=2&b=1 获取 a 的多个值。
gin中提供了QueryArray获取多个值，但是 rfc3986 没有定义服务端的实现，很多框架在解析的时候不一致，有些只使用第一个值或最后一个值。
所以我不确定它是否需要在RequestContext中实现，但我希望有办法获到它。

 ctx.QueryArgs().PeekMulti("a")

refer to https://github.com/cloudwego/hertz/pull/569/files and do you have a real world example of this use?

[a631807682]

refer to #569 (files) and do you have a real world example of this use?

Do you mean I need to describe this scenario in a test like https://github.com/cloudwego/hertz/pull/569/files#diff-6b0ef71f167bc3e1767a55944dc08d8cfb025629780b5cfcceb1cbe21e668e21R577 ?
Or do I need to add relevant code samples in the PR's description?

Reference code implementation

Sorry, I still don't get your point, can you tell me what aspect of PR implementation I need to refer to?

1. Is it about api design?
   We need to provide this api on RequestContext? There are two different considerations here, and the current implementation is the first one, please let me know if there is any problem.
   Added ctx.QueryMulti() gofiber/fiber#288 (comment)
   Implement QueryArray and PostFormArray methods gin-gonic/gin#570
2. Are there performance concerns?
   QueryArgs will only be parsed once, this method is not much different from GetQuery
3. Did not describe the real usage scenario?
   Do I need to add tests for multiple parameter requests to describe it?

The above is all my guesswork, I'd like some clear advice to let me know what I should do. 🙏
