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

Version

v22.14.0

Platform

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

Subsystem

No response

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.

Ejecuta la canalización de PowerShell reportada en Windows y, a continuación, inspecciona las comprobaciones específicas de la plataforma en lib/internal/fs/utils.js alrededor de las líneas 538-541. Determina por qué la detección de FIFO excluye las tuberías de Windows y verifica que stat.isFIFO() devuelva true en el caso de la entrada estándar canalizada, sin cambiar otras comprobaciones de tipos de archivo.
