feat：Prettier log output with log src file and line, looks like:

Thanks very much for this PR!
It's a neat feature to print the filename/line/function while logging and is very useful in certain situations.
However, for engine development, we prefer to keep the flexibility of each function. For example, maybe the developers don't want to output the above info to keep the simplicity of the logs, or some projects just need the log file's size as small as possible.
Therefore, we recommend implementing this feature in individual projects as needed, rather than in the engine.

Could this become a alternative log macro rather than the default one?

I think it's OK, but no idea about a proper naming.

1. 该方法相比于 C++ 更适合 C, C 使用 strrchr(), C++ 可以考虑使用 std::string_view.
2. 这种判断方法不适用于处理 Windows 的路径, 比如在 MSVC 中宏 __FILE__ 的值.

1. 这里其实用到了c++14 起的一个特性，constexpr 函数的编译期计算，可以看这里 https://godbolt.org/z/jjYqfjz7s ， O1级别以上的优化都会在编译期算出表达式，也就是执行期不会call function
   
2. 没有理解
3. 确实，只做了简单的测试，用 std::filesystem::path::preferred_separator替代即可

[ShenMian]

没注意到 constexpr, 抱歉. strrchr() 确实不支持, 不过 std::string_view 需要使用到的成员函数应该支持.

[ShenMian]

static constexpr std::string_view FileName(std::string_view path)
{
    return path.substr(path.find_last_of(std::filesystem::path::preferred_separator) + 1);
}

仅供参考.

Maybe make log pattern configurable

feat:

1. 使用Pilot自带的JSON序列化功能实现配置读取，替换原有的ini，简化代码，方便增加配置项
2. 令log pattern可配置，具体配置内容见 pattern-flags
