hw/core: Use a callback for target specific query-cpus-fast information

For being able to create a universal QEMU binary one day, core
files like machine-qmp-cmds.c must not contain any "#ifdef TARGET_..."
parts. Thus let's provide the target specific function via a
function pointer in CPUClass instead, as a first step towards
making this file target independent.
