kernel/amd64: Update arch(9)

This commit cleans up arch(9) as a few things were
noticed. First, it would make sense to identify cores (described by
the cpu_info structure) in every arch ported, thus
the lapic_id has been changed to id so it can be shared. Some
annotations have also been added for the sake of clarity. The manpage
for arch(9) has also been cleaned up.
