New witness calculation and DA config (#436)

## 📝 Summary

New witness calculation algo.
DA config.
Reserve space for builder_tx in block_da_size.

Note:
If da_config.max_da_tx_size is too small, execute function of OpBuilder
will panic, because it's improssible to insert builder transaction.
estimate_builder_tx_da_size may be a little bit heavy, maybe we could
precompute tx size for builder_tx and reuse it
