Reject a set_code tx one gas below the (now regular-only) intrinsic.

Under EIP-2780 the authorization intrinsic is entirely regular (the state-dependent costs moved to the top frame), so the intrinsic gas the transaction must cover is exactly fork.transaction_intrinsic_cost_calculator()(auth_list). Sweeping num_auths and pinning gas_limit at intrinsic - 1 catches an implementation that omits the repriced per-authorization base cost from the pre-validate check.
