gh-92301: subprocess: Prefer close_range() to procfs-based fd closing (#92303)
#92301: subprocess: Prefer `close_range()` to procfs-based fd closing.
`close_range()` is much faster for large number of file descriptors, e.g.
4 times faster for 1000 descriptors in a Linux 5.16-based environment.
We prefer close_range() only if it's known to be async-signal-safe.
