BACKPORT: arch: add pidfd and io_uring syscalls everywhere

Browse Source 
Add the io_uring and pidfd_send_signal system calls to all architectures.

These system calls are designed to handle both native and compat tasks,
so all entries are the same across architectures, only arm-compat and
the generic tale still use an old format.
