Implement `ContractBytecodeReadableKVState`

[bilyana-gospodinova]

Description: As part of the implementation for the reusable services we need to implement ContractBytecodeReadableKVState. It reads the contract's runtime bytecode and converts it to Bytecode PBJ type. This PR copies Utils from https://github.com/hashgraph/hedera-mirror-node/pull/9414 which is not merged yet.

Fixes https://github.com/hashgraph/hedera-mirror-node/issues/9255
