18369730b9 Refactor OEMCrypto_SetDecryptHash 
The current implementation of OEMCrypto_SetDecryptHash gives developers
flexibility to use different types of hashes. However, all the
implementations we have seen thus far use crc32. Because of this, crc32
should be sufficient and we can refactor OEMCrypto_SetDecryptHash to
only use the crc32 hash.

53fe55cb72 Clean up fuzz helper classes 
- Remove OEMCrypto state changes hidden in constructors and destructors.
- Use composition instead of inheritance to structure classes.
- Avoid calling non-trivial destructors for objects with static
  lifetime.
