virt: enable detecting QEMU (TCG) via CPUID (#6399)
QEMU >= 2.10 will include a CPUID leaf with value "TCGTCGTCGTCG"
on x86 when running with the TCG CPU emulator:
https://lists.gnu.org/archive/html/qemu-devel/2017-07/msg05231.html
Existing methods of detecting QEMU are left unchanged for sake of
backcompatibility.
