希望添加windows下Intel编译器支持（icx）

[Altina-oz]

你在什么场景下需要该功能？

windows下使用oneapi icx

测试代码（抄的cppreference）
#include

#ifdef PARALLEL
#include
namespace execution = std::execution;
#else
enum class execution { seq, unseq, par_unseq, par };
#endif

void measure([[maybe_unused]] auto policy, std::vectorstd::uint64_t v)
{
const auto start = std::chrono::steady_clock::now();
#ifdef PARALLEL
std::sort(policy, v.begin(), v.end());
#else
std::sort(v.begin(), v.end());
#endif
const auto finish = std::chrono::steady_clock::now();
std::cout << std::chrono::duration_caststd::chrono::milliseconds(finish - start)
<< '\n';
};

int main()
{
std::vectorstd::uint64_t v(1'000'000);
std::mt19937 gen {std::random_device{}()};
std::ranges::generate(v, gen);

measure(execution::seq, v);
measure(execution::unseq, v);
measure(execution::par_unseq, v);
measure(execution::par, v);

}

描述你认为的候选方案

No response

其他信息

似乎必须要在环境变量里增加oneapi_root不然不知道怎么找setvars.bat

cc和cxx的driver似乎"icx-cl.exe"比较和现有的兼容，直接"icx.exe"会使得有的flag进不去，虽然Intel推荐使用icx.exe。

暂时没环境，可以参考下 ifort 的实现

• https://github.com/xmake-io/xmake/blob/master/xmake/toolchains/ifort/check.lua
• https://github.com/xmake-io/xmake/blob/master/xmake/modules/detect/sdks/find_ifortenv.lua

改进下 icx 实现，提个 pr 过来

There is no environment for now, you can refer to the implementation of ifort

• https://github.com/xmake-io/xmake/blob/master/xmake/toolchains/ifort/check.lua
• https://github.com/xmake-io/xmake/blob/master/xmake/modules/detect/sdks/find_ifortenv.lua

Improve the icx implementation and submit a PR.

暂时没太多时间调这个，可以参考这个 patch 自己调下。#5132

[waruqi]

先这样吧，凑活着能用了。。#5132

剩下的有啥改进，直接来 pr
