qemu: add qemu vga devices caps and one cap to mark them usable

QEMU_CAPS_DEVICE_QXL          -device qxl
QEMU_CAPS_DEVICE_VGA          -device VGA
QEMU_CAPS_DEVICE_CIRRUS_VGA   -device cirrus-vga
QEMU_CAPS_DEVICE_VMWARE_SVGA  -device vmware-svga

QEMU_CAPS_DEVICE_VIDEO_PRIMARY  /* safe to use -device XXX
                                 for primary video device */

Fix a typo in qemuCapsObjectTypes, the string 'qxl' here
should be -device qxl rather than -vga [...|qxl|..]
