Designed for contract wallet, removes safeTransferFrom, approve, setApprovalForAll, getApproved, isApprovedForAll functions from ERC-721
ERC-165 interface ids
Computed here as the XOR of the selectors each interface defines.

The spec asserts 0xc1b31357 for IERC7561, which its own interface does not produce.
Asserted value is a copy-paste of ERC-7196's id, the XOR of totalSupply(), balanceOf(address) and transfer(address,uint256). ERC-7561 declares no transfer(address,uint256).
