[WIP] Fake bls at runtime (#735) 
* Initial implementation of runtime bls skipping.

Add libnfuzz skipBLSValidation handling, check that it propagates.

* Rename skipBLSValidation -> skipBlsValidation, start skipStateRootValidation
* Replace skipValidation flags with more granular flags.

Also added skipBlockParentRootValidation flag
Mainly replaced with skipBlsValidation but also StateRoot or
BlockParentRootValidation flags where appropriate.

* Adjust interop test to pass when skipping merkle validation.
* Stop skipping validation for mainchain_monitor.
* Remove comment.
* Also skipMerkleValidation for test_beacon_chain_db.

Nathaniel Jensen a37fac864f Update exception handling based on discussions. 
ValueErrors identified as associated with logging and are classed as a
failure rather than expected behavior.

Nathaniel Jensen e356ae0405 Remove skipValidation for block, block_header handlers. 
As differences are being identified due to it skipping block parent root
validation.

Nathaniel Jensen e795234504 Nfuzz to set runtime skipValidation flag where possible. 
Note: this does more than just disable bls - see #407,
so is not strictly consistent with other `beacon-fuzz`
implementations.

Nathaniel Jensen a08db4b311 Implement nfuzz_block_header nfuzz_attester_slashing harnesses. 
Add notes where not certain whether the error should crash or return
false.

Update header.

Nathaniel Jensen 5978f09261 Allow defects and assertions to propagate in fuzzing harnesses. 
Add some slight libnfuzz readme notes.

Adjust exception tagging appropriately.

Nathaniel Jensen 0d764d87af Raise exception when failing deserialization instead of returning false. 
Fuzzer preprocessing should provide valid ssz.
