EVM/Exec: clear contract storage before execution on contract creation

Context

In a situation where a smart contract was deleted (SELFDESTRUCT), its code, balance and nonce are set to zero, but its storage remains unchanged. When a contract is created at the same address the storage must be cleared before its execution, a small scenario with anvil should showcase this behaviour. There's a test in the suite that covers this issue as well, see ethereum/tests/GeneralStateTests/Shanghai/stSStoreTest/InitCollision.json.
