Instead of having KVM_HAVE_MCE_INJECTION optionally defined,
always define KVM_ARCH_HAVE_MCE_INJECTION for each target,
and set KVM_HAVE_MCE_INJECTION if it is not zero.
It is now clearer for KVM targets to detect if they lack the
MCE injection implementation. Also, moving headers around
is no more painful, because if a target neglects to define
KVM_ARCH_HAVE_MCE_INJECTION, the build will fail.

I'd rather keep "cpu-param.h" simple/short.
Is a per-target "kvm-param.h" any better?
Or per-target "accel-param.h"? For example TCG_GUEST_DEFAULT_MO
is TCG specific and could also go there. Otherwise it will go
in "cpu-param.h".
