xen, xen-tools: add recommendation for Qemu for non-hvm x86

Browse Source 
The Spectre and Meltdown mitigations for Xen run PV guests within
HVM virtual machines, so Qemu is no longer only needed for systems
configured to run HVM guests.

With the split xen hypervisor and tools recipes, the bios dependencies
belong in the tools recipe, so move them and replace the hvm
PACKAGECONFIG option with the recommendation based on target arch.
