[RFC 16/52] plugins: Use generic topology name and helper

[Zhao Liu]

From: Zhao Liu <zhao1....@intel.com>

As the generic code, here we should respect the different topologies:
smp or hybrid.

So rename qemu_info_t.system.smp_vcpus to qemu_info_t.system.vcpus to
decouple with smp topology.

And use generic topology helpers to get topology information.
