hw/core: Make CPU topology enumeration arch-agnostic

Cache topology needs to be defined based on CPU topology levels. Thus,
define CPU topology enumeration in qapi/machine.json to make it generic
for all architectures.

To match the general topology naming style, rename CPU_TOPO_LEVEL_* to
CPU_TOPOLOGY_LEVEL_*, and rename SMT and package levels to thread and
socket.

Also, enumerate additional topology levels for non-i386 arches, and add
a CPU_TOPOLOGY_LEVEL_DEFAULT to help future smp-cache object to work
with compatibility requirement of arch-specific cache topology models.
