Subject: [PATCH] Convert max file name length to 255 (#30489) (#30504)

Backport #30489 by @yp05327

Quick/Partly fix #29907

In Linux and MacOS, by default the max file name length is 255.
In windows, it depends on the version and settings, and has no file name
length limitation, but has path length limitation.
By default it is 260, considering path length is longer than filename,
so I think it is ok to do this.

For Windows, see
https://learn.microsoft.com/windows/win32/fileio/maximum-file-path-limitation?tabs=registry
For Linux, see

For MacOS, see
