No Config Debugging errors when multiple vscode windows are open

If I use the no config debugging feature with multiple vscode windows open, all of them try to start debugging. Whichever is first suceeds and the rest throw a Server[pid=xxxx] is already being debugged error.

The cause for this is that the extension watches the .noConfigDebugAdapterEndpoints dir and starts debugging if any file appears in it not just if the specified file (VSCODE_DEBUGPY_ADAPTER_ENDPOINTS) is created. Each window has a separate endpoint file in the .noConfigDebugAdapterEndpoints dir, but due to watching for any file, every window will start debugging.

从 src/extension/noConfigDebugInit.ts 第 95-97 行附近开始，阅读 .noConfigDebugAdapterEndpoints 目录是如何被监视的。确认只有在创建了由 VSCODE_DEBUGPY_ADAPTER_ENDPOINTS 指定的端点文件时才会开始调试，从而使彼此独立的 VS Code 窗口不会对对方的文件作出响应。
