stat.isFIFO() is wrongly marked as always false on Windows, even when piping into a node process

Version

Platform

Microsoft Windows NT 10.0.26120.0 x64 [although this is on ARM64]

Subsystem

What steps will reproduce the bug?

Running echo '{}' | node -e 'console.log(require("fs").fstatSync(0).mode)' in PowerShell (as cmd doesn't seem to support pipes via the usual syntax) returns 4096, and checking fs.constants, S_IFIFO is set to 4096.

How often does it reproduce? Is there a required condition?

Seems to be all the time on Windows when you try to pipe something in, which is due to a (I assume legacy?) check here: https://github.com/nodejs/node/blob/c3b6f949748b49ef25b0239bd4582d29976fdbad/lib/internal/fs/utils.js#L538-L541

What is the expected behavior? Why is that the expected behavior?

On Windows, stat.isFIFO() should correctly handle pipes and stat.isFIFO() should correctly return true when piped in

What do you see instead?

stat.isFIFO() always returns false on Windows, even if the mode has the flag set

Additional information

I would love to submit a PR to fix this, but I am not sure if those checks are there for a reason or for legacy purposes (it seems that at least the S_ISFIFO is now exposed but it wasn't before [?]), and if it can be edited safely.

在 Windows 上运行报告中的 PowerShell 管道，然后检查 lib/internal/fs/utils.js 第 538-541 行附近的平台特定检查。确定 FIFO 检测为何排除 Windows 管道，并验证在通过管道传入 stdin 的情况下 stat.isFIFO() 返回 true，同时不更改其他文件类型检查。
