[CHAIN MAINTENANCE] Use polkadot-parachain-lib

[kianenigma]

Hey there!

Based on your former feedback, one of the features of polkadot-parachain-lib is that it allows for u64 block number. This means you can remove your node implementations entirely, use polkadot-parachain-lib, and create your custom instances of it with your chain-spec and block number type.

See here for an example

Be aware that we might rename the crates, but otherwise the API is stable.

paritytech/polkadot-sdk#5566

Do you need any help? please ping me or @serban300 :)

Although, I just realized that this crate is no released, so you might need to wait for the next polkadot-sdk release :)

It would also probably mean we can now split node and runtime repos, so that we can move faster on the node side without having to always catch up with the runtime.

You can also stay in the same repo, but start using the the proposed method above.
