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.

In null/golden context there are multiple state commands where
the actual state is always zero. For more compact batch representation
add a macro which just emits command and the rest of the state as zero.
v2: - Be more verbose about length bias (Bradley Volkin)
- strip out unrelated state_offset declaration (Bradley Volkin)

Currently our kernel side buffer object is only one page.
Limit the amount of dwords to 1024 to enforce this.

Instead of building batch directly to memory, build into cmd and
state arrays. This representation allows us more flexibility in batch
state expression and batch generation/relocation.
As a bonus, we can also attach the line information that produced the
batch data to help debugging.
There is no change in the output states produced. This can be considered
as a preparatory patch to help introduce gen8 golden state.

Generate valid (null) render state for each gen. Output
it as a c source file with batch and relocations.
