Embedded mainnet genesis state + load genesis.ssz from file (#8614)
* Update rules_go and fix proto conflicts

* gaz

* Update generated code

* First pass inclusion of using baked states

* more emptypb fixes

* remove testnet genesis files, only embed mainnet

* Refactoring for SaveGenesisData, fix tests that use mainnet config but do not support mainnet genesis values

* a bit more refactoring, load genesis from a file. Needs tests still

* Add method to ensure an embedded genesis file also has the appropriate genesis block

* gofmt

* more clear error

* Check genesis fork version to ensure testnet config matches genesis file

* viz

* test for SaveGenesisData

* More genesis db method tests

* Merge

* Minor tweaks, lint, fmt, etc

* Add more test to genesis db methods

* Revert beacon-chain/state/stateV0/BUILD.bazel

* Update beacon-chain/db/iface/errors.go

* PR feedback

* Update beacon-chain/db/kv/genesis.go

Co-authored-by: terence tsao <terence@prysmaticlabs.com>

* fmt.Errorf works better for nil errors
