[EVM-Equivalence-YUL] Simplify EXTCODESIZE

[0xVolosnikov]

Instead of calling an oracle and decommiting the code, the length can be obtained from the hash. Using the same logic as in CodeOracle.yul. In addition, we can use this logic for both types of contracts, which allows us to remove the extra call to check the contract type.

Result observed:
