Test contract creation with state gas from reservoir or gas_left.

Contract creation charges intrinsic state gas for the new account (new-account state gas). When gas_above_cap is True, extra gas beyond TX_MAX_GAS_LIMIT feeds the reservoir. When False, all state gas comes from gas_left (reservoir is zero).
