Now incorporate is fixed to copy across the properties we need in the
superclass, we don't need to do the subclass ->probe().
Note, we still need to do the subclassed ->probe() when using
FU_UDEV_DEVICE_FLAG_VENDOR_FROM_PARENT or when looking at properties
on the parent device.
This also removes the spurious 'already set GType to FuVliUsbhubDevice,
ignoring FuVliUsbhubDevice' messages when running the daemon.
Provide a device instance builder that allows plugins to easily
create multiple instance IDs based on parent attributes.
Also fix a lot of the instance ID orders, so that we add more generic
IDs first, and more specific IDs after.
