Replace IPC::File / AutoCloseFileDescriptor / MessageFileType in the IPC message pipeline with a new IPC::Attachment class. This wraps a file descriptor transferred alongside IPC messages, and provides a clean extension point for platform-specific transport mechanisms (e.g., Mach ports on macOS) that will be introduced later.
