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.

Changes since Patch v1:
* Dropped prefix of CpuTopologyLevel enumeration. (Markus)
* Rename CPU_TOPO_LEVEL_* to CPU_TOPOLOGY_LEVEL_* to match the QAPI's
generated code. (Markus)
Changes since RFC v2:
* Dropped cpu-topology.h and cpu-topology.c since QAPI has the helper
(CpuTopologyLevel_str) to convert enum to string. (Markus)
* Fixed text format in machine.json (CpuTopologyLevel naming, 2 spaces
between sentences). (Markus)
* Added a new level "default" to de-compatibilize some arch-specific
topo settings. (Daniel)
* Moved CpuTopologyLevel to qapi/machine-common.json, at where the
cache enumeration and smp-cache object would be added.
- If smp-cache object is defined in qapi/machine.json, storage-daemon
will complain about the qmp cmds in qapi/machine.json during
compiling.
Changes since RFC v1:
* Used QAPI to enumerate CPU topology levels.
* Dropped string_to_cpu_topo() since QAPI will help to parse the topo
levels.
