tools/null_state_gen: Add Gen8 golden state
Previously we didn't have a clear understanding what is necessary
for a pipeline state to be properly initialized. So we had to improvise
and use a stripped out render copy.
Now we have a more clear understanding so switch out render copy based
frankenstate to state we can call golden state.
v2: - export intel_batch_state_offset
- add 3DSTATE_RASTER (Bradley Volkin)
