tests: Add baseline tests for automatic PHB usage

These tests demonstrate that, while it's now possible for the
user to create PHB explicitly and manually assign devices to
them, libvirt still defaults to extending the guest PCI
topology using PCI bridges and making suboptimal device
placement choices.

The next few commits will improve on these behaviors and the
tests outputs will automatically be updated to reflect this.
