Upgrade to v1.4.0-beta.3 (#4862)

## Issue Addressed

Makes lighthouse compliant with new kzg changes in https://github.com/ethereum/consensus-specs/releases/tag/v1.4.0-beta.3

## Proposed Changes

1. Adds new official trusted setup
2. Refactors kzg to match upstream changes in https://github.com/ethereum/c-kzg-4844/pull/377
3. Updates pre-generated `BlobBundle` to work with official trusted setup. ~~Using json here instead of ssz to account for different value of `MaxBlobCommitmentsPerBlock` in minimal and mainnet. By using json, we can just use one pre generated bundle for both minimal and mainnet. Size of 2 separate ssz bundles is approximately equal to one json bundle cc @jimmygchen~~ 
Dunno what I was doing, ssz works without any issues  
4. Stores trusted_setup as just bytes in eth2_network_config so that we don't have kzg dependency in that lib and in lcli.
