Update lodestar ecosystem to ES modules (ESM)

[wemeetagain]

Once lodestar dependencies move to ES modules only, we can't upgrade unless we also move. Since ES modules are the future, we should migrate when possible.

Current progress

• ChainSafe/lodestar: ESM Support #3978
• ChainSafe/lodestar: Update libp2p to ESM version #4114

libp2p

• ChainSafe/js-libp2p-gossipsub: fix!: update to esm only export js-libp2p-gossipsub#236
• ChainSafe/js-libp2p-noise: feat: update to new libp2p interfaces js-libp2p-noise#134
• ChainSafe/discv5: feat!: convert to esm only discv5#184

bls

• ChainSafe/bls: ESM Support bls#121
• ChainSafe/blst-ts: N/A

ssz

• ChainSafe/ssz: Stop supporting CommonJS builds ssz#439, chore: remove support for CJS ssz#440

@wemeetagain Does #3978 conclude the upgrades to ESM? If so, we can close this.

[wemeetagain]

We will migrate our other libraries over to ESM too. ssz monorepo packages, bls packages, discv5, etc.
Lower priority tho, no urgency

[wemeetagain]

• Update libp2p to ESM version #4114 is related

[philknows]

We should continue discussing this for https://github.com/ChainSafe/ssz

[wemeetagain]

I don't think its worth keeping this open. There are a few libraries we maintain that are commonjs that likely can't be moved without massive pain, and there are libraries that are commonjs that are low priority to change (eg libraries using napi-rs, which currently only supports commonjs).

closing for now

Re-opening as a decision was made to fully drop support for common JS modules for the remaining Lodestar ecosystem to minimize maintenance complexity.
