DNS: Add new nonIPQuery "reject"

[Fangliding]

close #4819
Windows上的nslookup也会卡(因为ptr查询)

[yuhan6665]

感谢佬！感觉这块的逻辑有点奇怪 不过好像没有更简单的办法先这样吧

[stonegr]

good, thanks

[RPRX]

我感觉把这个设为 default 更好？

[Meo597]

现代浏览器还会发送 https 查询 rfc9460
drop 其实并不算明智选择
你是否考虑让非 a/aaaa 查询也走 dns 模块，但不缓存？
这样可以策略选路，看起来更完美

I have tried xray-core (commit 1976d02) with this feature.
After a day or so panic occurred:

I wasn't able to reproduce problem (server has no logs and many users, no idea what triggered this)
@Fangliding friendly ping, since there is a chance that panic message contains enough info to understand what happened
