[_] Remove unused or duplicated functions

[TamaraFinogina]

Description

Remove duplicated functions that only differ in applying type transformations:

1. '@noble/hashes/utils.js' is a smaller import than the same from post-quantum
2. deriveSymmetricKeyFromTwoKeysAndContext is not used anymore
3. I removed the HEX version from deriveKey and hash; converters are in utils, so it's a bit redundant
4. mac and keyedHash is the same, hence redundant
5. deriveWrappingKey is not used anymore
