fix(tests): accept tx- or block-level exception for over-budget block (EIP-7778) (#2949)

In test_multi_transaction_gas_accounting, a block whose included transaction
exceeds the remaining block gas was expected to fail only with the block-level
BlockException.GAS_USED_OVERFLOW. A client may legitimately report the same
condition at the transaction level: EELS raises GasUsedExceedsLimitError (an
InvalidTransaction subclass) when `tx.gas > gas_available`, and evmone reports
it as a rejected transaction (GAS_LIMIT_REACHED).

List both BlockException.GAS_USED_OVERFLOW and
TransactionException.GAS_ALLOWANCE_EXCEEDED as acceptable so either
categorization passes.
