/**
* @dev Executes the calls in `executionData`.
* Reverts and bubbles up error if any call fails.
*
* `executionData` encoding:
* - If `opData` is empty, `executionData` is simply `abi.encode(calls)`.
* - Else, `executionData` is `abi.encode(calls, opData)`.
* See: https://eips.ethereum.org/EIPS/eip-7579
*
* Supported modes:
* - `bytes32(0x01000000000000000000...)`: does not support optional `opData`.
* - `bytes32(0x01000000000078210001...)`: supports optional `opData`.
*
* Authorization checks:
* - If `opData` is empty, the implementation SHOULD require that
* `msg.sender == address(this)`.
* - If `opData` is not empty, the implementation SHOULD use the signature
* encoded in `opData` to determine if the caller can perform the execution.
*
* `opData` may be used to store additional data for authentication,
* paymaster data, gas limits, etc.
*
* For calldata compression efficiency, if a Call.to is `address(0)`,
* it will be replaced with `address(this)`.
