[new] security/openssl/3.1

Released today: https://www.openssl.org/news/openssl-3.1-notes.html

This doesn't need to make the 7.3 release, but I guess it would be nice
to have. Since it is quarantined under eopenssl31, I don't expect any
impact on ports.

The changelog contains nothing particularly exciting except that there's
initial RiscV assembly support. It looks like that assembly is already
x-only clean, so I left the noexeconly exemption.

It would be nice if someone could run regress on riscv64 to confirm.

I took the 3.0 port, attempted to adjust the PKGSPEC line, dropped a
@conflict from the PLIST, ran s/30/31/g over the Makefile and reset the
SHLIBVER to 0.0 (should that be ahead of 3.0?). That's about it.

I refreshed the patches and needed to adjust the armv8 assembly a little.

Passes regress on an amd64 machine with PKU and arm64 (beware, it takes
forever).


There's one failing test case on sparc64. Not sure if that's new.
I'll look more closely:
