qemu_capabilities: Report Hyper-V Enlightenments in domcapabilities

Browse Source 
Inside of qemuCaps (for the corresponding accelerator) we have
full host CPU expansion stored, among with supported Hyper-V
Enlightenments. To report them in the domain capabilities, we
just have to pick those starting with "hv-" and see if we know
them.

You may notice that neither of our domaincapsdata test shows any
enlightenment. This is because the test works by parsing
corresponding qemucapabilitiesdata/caps_*.xml file and none of
these store the full host CPU expansion (hostCPU.fullQEMU)
because that is runtime piece of information and not formatted
into virQEMUCaps XML.
