[roll] Roll fuchsia [zxsh] Add Process Spawning and IPC Utilities

Implement process spawning (`spawn_command`), IPC pipe creation
(`make_pipe`), file descriptor reading (`read_fd_to_end`), and FD
spawning action mapping (`clone_fd_to_action`). Resolves binary paths
against the shell `PATH` variable and sets up process namespaces and
environment. Includes comprehensive unit tests validating output and
achieving 100% test coverage.
