[3.12] gh-109981: Fix support.fd_count() on macOS 14 (GH-112797) (#112824)
gh-109981: Fix support.fd_count() on macOS 14 (GH-112797)
Use scanning "/dev/fd/" on macOS in support.fd_count(). That's both more efficient than scanning all possible file descriptors, and avoids crashing the interpreter when there are open "guarded" file descriptors.
"Guarded" file descriptors are a macOS feature where file descriptors used by system libraries are marked and cause hard crashes when used by "user" code.
