util/qemu: Add additional config file for QEMU/Q35

The `q35-alpine.cfg` adds a lot of PCIe devices to resemble the
topology inside an Intel Alpine Ridge Thunderbolt controller.
By no means could this be detected as such a controller. But
having a real-world example of such a topology can help to
test the allocator and other algorithms on a deeper tree.

It adds two levels of PCIe switches (`alpine-root` and
`alpine-1`), and two endpoints (a `pci-testdev` and an xHCI
controller).

It can be added to the default `q35-base.cfg` config, e.g.
with:

$ make qemu QEMU_EXTRA_CFGS=util/qemu/q35-alpine.cfg
