Solidity Interface & Canonical Declaration
function execTransaction(address to, uint256 value, bytes calldata data, uint8 operation, uint256 safeTxGas, uint256 baseGas, uint256 gasPrice, address gasToken, address payable refundReceiver, bytes memory signatures) external payable returns (bool success)
在收集齐满足阈值要求的全部所有者多签签名后，执行目标多签交易与资金划转。
理论基础执行 Gas： 75,000 ~ 280,000 gas
返回值类型： bool
