arch: add pidfd and io_uring syscalls everywhere

This comes a bit late, but should be in 5.1 anyway: we want the newly
added system calls to be synchronized across all architectures in
the release.

I hope that in the future, any newly added system calls can be added
to all architectures at the same time, and tested there while they
are in linux-next, avoiding dependencies between the architecture
maintainer trees and the tree that contains the new system call.

    arch: add pidfd and io_uring syscalls everywhere

    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.

Is "everywhere" really means everywhere?
The reason I'm asking this question is that sh64 seems to be excluded:
arch/sh/kernel/syscalls_64.S hasn't got any syscall entries since commit
v4.8-rc1~15^2~3.  Is sh64 supported in any way at all?

sh64 is dead, the only reason those files are still there is because nobody
has bothered to create the patch to remove them.

It has not been possible to even build an sh64 kernel for many years,
and I'm sure none of the prototypes have been turned on for even longer
if they are still in someone's board pile.
