unix: regenerate on FreeBSD 12.3

Switch mksysnum to use https://cgit.freebsd.org/src/plain/sys/kern/syscalls.master?h=stable/12.
Also remove the SAL 2.0 annotations.

remove FreeBSD 11 and below 64bit inode compatibility shims

Drop the errors_freebsd_GOARCH.go files.

Drop PTRACE_* and additional (arch specific) consts added as part of golang.org/cl/179099 to types_freebsd.
Add <sys/ptrace.h> to mkerror.sh for FreeBSD instead.

Run mkall.sh on FreeBSD 12.3 on amd64 and arm64 hosts with i386 and armv7 jails
for all supported arches.

Updates golang/go#53280
