Add kernel_irqchip=split/on to the QEMU command line
and a capability that looks for it in query-command-line-options
output. For the 'split' option, use a version check
since it cannot be reasonably probed.
https://bugzilla.redhat.com/show_bug.cgi?id=1427005
Due to the extra architecture-specific logic, it's already
necessary for users to call virQEMUCapsHasPCIMultiBus(),
so the capability itself is just a pointless distraction.
CPU models (and especially some additional details which we will start
probing for later) differ depending on the accelerator. Thus we need to
call query-cpu-definitions in both KVM and TCG mode to get all data we
want.
Tests in tests/domaincapstest.c are temporarily switched to TCG to avoid
having to squash even more stuff into this single patch. They will all
be switched back later in separate commits.

Do all the stuff for the vhost-scsi capability in QEMU,
so it's in place for our checks later.

If QEMU in question supports QMP, this capability is set if
QEMU_CAPS_DEVICE_QXL was set based on existence of "-device qxl". If
libvirt needs to parse *help*, because there is no QMP support, it
checks for existence of "-vga qxl", but it also parses output of
"-device ?" and sets QEMU_CAPS_DEVICE_QXL too.
Now that libvirt supports only QEMU that has "-device" implemented it's
safe to drop this capability and stop using it.

This patch simplifies QEMU capabilities for QXL video device. QEMU
exposes this device as *qxl-vga* and *qxl* and they are both the same
device with the same set of parameters, the only difference is that
*qxl-vga* includes VGA compatibility.
Based on QEMU code they are tied together so it's safe to check only for
presence of only one of them.
This patch also removes an invalid test case "video-qxl-sec-nodevice"
where there is only *qxl-vga* device and *qxl* device is not present.

The only QEMU versions that don't have such capability are <0.12,
which we no longer support anyway.
Additionally, this solves the issue of some QEMU binaries being
reported as not having such capability just because they lacked
the {kvm-}pci-assign QMP object.
