ERC4337Utils: Update the hash function to call getUserOpHash on the specified entrypoint and add an ENTRYPOINT_V08 constant. (#5614)

Hashes: Expose efficientKeccak256 for hashing non-commutative pairs of bytes32 without allocating extra memory. (#5442)
Initializable: Add _initializableStorageSlot function that returns a pointer to the storage struct. The function allows customizing with a custom storage slot with an override. (#5526)
P256: Adjust precompile detection in verifyNative to consider empty returndata on invalid verification. Previously, invalid signatures would've reverted with a MissingPrecompile error in chains with RIP-7212 support. (#5620)
