tools/null_state_gen: Add macro to emit commands with null state

Browse Source 
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)
