v3d: Pass the version being generated to the pack generator script.

Browse source 
It turns out that most V3D versions change very few packets, so keeping
separate copies of the XML per version makes changing the XML a pain as
you have to replicate your changes to each one.  This is the start of
changing it so that one XML can generate headers for multiple versions.
