The preceding commits define the future-pidfd lifetime, configuration, and run state machine without making them reachable from userspace. Each preparatory step therefore remains bisectable without exposing a partial process builder.
Make pidfd_open(0, PIDFD_EMPTY) create a taskless future pidfd and expose pidfd_config() and pidfd_spawn_run(). Add the syscall declarations and table entries together so the complete initial interface becomes reachable at one commit boundary. Synchronize the lagging arm64 AArch32 perf mirror through the current syscall table while adding the builder entries.
