Fix gloas consensus-specs discrepancies and add EF tests

- Fix DOMAIN_BEACON_BUILDER value (0x1B -> 0x0B per spec)
- Add DOMAIN_PROPOSER_PREFERENCES (0x0D)
- Add min_builder_withdrawability_delay config (4096 epochs)
- Add MaxBuildersPerWithdrawalsSweep to EthSpec trait
- Add gloas_only/gloas_and_later handlers for EF tests
- Add SSZ static tests for all new Gloas types
