hw/sysbus: Introduce TYPE_DYNAMIC_SYS_BUS_DEVICE

Some TYPE_SYS_BUS_DEVICEs can be optionally dynamically
plugged on the TYPE_PLATFORM_BUS_DEVICE.
Rather than sometimes noting that with comment around
the 'user_creatable = true' line in each DeviceRealize
handler, introduce an abstract TYPE_DYNAMIC_SYS_BUS_DEVICE
class.
