Hardcoded GenesisValidatorsRoot (#14365)

* hardcoded GenesisValidatorsRoot

* added in mainnet.config

* updated desc

* added it in all testnets

* minor change

* added roots instead of empty and fn to compute byte32 from hex

* added in e2e testnet_config

* fixed test

* minor fix

* removed fn and added bytes output directly

* Add test for genesis validator root mainnet value

* removed root from minimal and testnet

* removed root

* Update CHANGELOG.md

* Fix bazel package visiblity
