panfrost/genxml: Decode Bifrost index-driven vertex jobs

Browse source 
Bifrost has a new type of job called 'index-driven vertex', which takes
in two shaders. The primary shader, called for all values, performs
position shading to a cacheline-aligned attribute buffer. The secondary
shader, called for values still live after culling, performs varying
shading.

It is the responsiblilty of the implementation to ensure that vertices
from different instances do not share a cacheline.
