Feat: add queryStrategy option for DNS

[Loyalsoldier]

Fixes #482
Fixes #297

根据 #749 的建议，重新实现。复原了 V2Ray 原本的接口。

Great! This is what I think is the best way to make sure that unseen codes won't break because of the modification of API. Unlike gRPC API, changing interface in Go is usually breaking, which should be avoid whenever possible.

@yuhan6665 @CalmLong 能否帮忙测试一下这个 PR 在 Android 上使用 FakeDNS 有没有 bug？我身边没有 Android 机 😂

[rurirei]

@Loyalsoldier seems ok.

[CalmLong]

我还没研究过FakeDNS😓主要是用不到。。

[Loyalsoldier]

@Loyalsoldier seems ok.

你测试了吗？我主要是不确定在 Android 手机上 FakeDNS 能不能跟 #696 保持一致，忽略 freedom outbound 和路由。

这条 commit 貌似会导致 fakedns 失效，无论我是否设置 queryStrategy 及设置 "UseIP" 、 "UseIPv4" ，fakedns 都无法对匹配的域名给出解析。
在 v4.37.1 上 revert 这条 commit 并编译使用则不再复现。

配置如下

系统 win10，具有v4，v6 双地址。

系统 ping google.com 时，会显示
Ping 请求找不到主机 google.com 。请检查该名称，然后重试。
如果 ping -4 google.com，就会得到正常的fakedns 地址（192.18.0.0/15）。
非常怀疑，由于 fakedns 向客户端返回的查询时win10 系统，会默认使用 IPv6 进行访问。

v2 dns设置
{ "dns": { "servers": [ { "address": "114.114.114.114", "domains": [ "domain:translate.google.cn" ] }, { "address": "fakedns", "domains": [ "geosite:greatfire", "geosite:gfw" ] }, { "address": "8.8.8.8", "domains": [ "geosite:greatfire", "geosite:gfw" ] }, "localhost" ], "queryStrategy": "UseIPv4" } }
