qapi: make s390x specific CPU commands unconditionally available

Browse source 
This removes the TARGET_S390X and CONFIG_KVM conditions from the
CPU commands that are conceptually specific to s390x. Top level
stubs are provided to cope with non-s390x targets, or builds
without KVM.

The removal of CONFIG_KVM is justified by the fact there is no
conceptual difference between running 'qemu-system-s390x -accel tcg'
on a build with and without KVM built-in, so apps only using TCG
can't rely on the CONFIG_KVM in the schema.
