Mismatch between TS simulator and circuit for kernel value output SLOAD_WRITE_OFFSET

[jeanmon]

This is a follow-up of #7135.
After fixing the above bug pertaining the AVM circuit, a run of the end-to-end test bench_prover.test.ts shows that some AVM proofs are still failing in the verification step.
After some investigation, it was noticed that all the 3 failing proofs have a mismatch between the public inputs fed to the verifier (generated by TS simulator) vs. the public inputs produced in the AVM trace in the proving step.

All the AVM proofs generated in this e2e test were re-ran in a debugger and the full transcript is in comment below.
We observe that the mismatch is always at index 144 which corresponds to START_SLOAD_WRITE_OFFSET.
The simulator (VERIF in logs) has generated some entry at index 144 while the AVM circuit does not generate any.
