Add FUZZING_BUILD_MODE_UNSAFE_FOR_PRODUCTION in PoW check

Browse Source 
To avoid PoW being a blocker for fuzz tests,
`FUZZING_BUILD_MODE_UNSAFE_FOR_PRODUCTION` is used in fuzz builds to
bypass the actual PoW validation in `CheckProofOfWork`. It's
replaced with a check on the last byte of the hash, which allows the
fuzzer to quickly generate (in)valid blocks by checking a single bit,
rather than performing the full PoW computation.

If PoW is the target of a fuzz test, then it should call
`CheckProofOfWorkImpl`.
