tablet: add a bustype event to the initial burst of tablet events

Browse source 
Just VID/PID is not enough, we need the bustype too. And since we now
have that event remove the mention of USB from zwp_tablet_v2.id.

The USB vendor and product IDs for the tablet device.
<description summary="tablet device vendor/product id">
The vendor and product IDs for the tablet device.
If the device has no USB vendor/product ID, this event is not sent.
The interpretation of the id depends on the wp_tablet.bustype.
Prior to version v2 of this protocol, the id was implied to be a USB
vendor and product ID. If no wp_tablet.bustype is sent, the ID
is to be interpreted as USB vendor and product ID.
If the device has no vendor/product ID, this event is not sent.
This can happen for virtual devices or non-USB devices, for instance.
This event is sent in the initial burst of events before the
wp_tablet.done event.
