In Swift 6 mode these were diagnosed as shared mutable global state (#75601). Mark them nonisolated(unsafe) across the libc overlays. Glibc/Musl/Android/WASI define them as computed vars backed by the _swift_stdlib_std* shims; Platform.swift covers OpenBSD, FreeBSD/PS4, and Windows. They are OpaquePointer where FILE is opaque (Musl, WASI, Android, OpenBSD) and UnsafeMutablePointer<FILE> elsewhere. Adds the StdioSendable regression test.
