Move global_vmstate from vga_common_init() parameter to VGACommonState
field. Set global_vmstate to true for isa vga devices, so nothing
changes here. virtio-vga and secondary-vga already set global_vmstate
to false so no change here either. All other pci vga devices get a new
global-vmstate property, defaulting to false. A compat property flips
it to true for older machine types.
With this in place you don't get a vmstate section naming conflict any
more when adding multiple pci vga devices to your vm.
