initialize genesis data asap at node start (#15470)

* initialize genesis data asap at node start

* add genesis validation tests with embedded state verification

* Add test for hardcoded mainnet genesis validator root and time from init() function

* Add test for UnmarshalState in encoding/ssz/detect/configfork.go

* Add tests for genesis.Initialize

* Move genesis/embedded to genesis/internal/embedded

* Gazelle / BUILD fix

* James feedback

* Fix lint

* Revert lock
