Helper function upgrade

[377960738]

1. 新增助手函数 run_path , 返回当前程序运行目录 (支持phar)

   /**
   * return the program execute directory
   * @param string $path
   * @return string
   */
   function run_path(string $path = '')
   {
   static $run_path = '';
   if (!$run_path) {
       $run_path = \is_phar() ? \dirname(\Phar::running(false)) : BASE_PATH;
   }
   return \path_combine($run_path, $path);
   }

2. 路径相关函数支持传入后续路径，不影响原有代码，具体如下

   
   # base_path 接参微调
   # 原 base_path(bool $return_phar = true)
   # 现 base_path(string|false $path = '')

app_path(string $path = '')

public_path(string $path = '')

config_path(string $path = '')

runtime_path(string $path = '')
