Move all runtime definitions to parachain-commons

[clangenb]

polkadot-v0.9.12 has introduced a new crate that unifies some type and constant definitions. However, we still have the redundant definitions inside the runtime (partly because they are still there in upstream too). We should remove the runtime definitions favoring the ones from the parachain-commons crate and. However, we should re-export them there!

• remove redundant defintions from runtime
• extend missing definitions in the parachain-commons
• re-export all definitions in the both runtimes.

Not really necessary for the epic, but given the amount of effort I think this is a very nice to have.

Obsolete since the runtime has been moved to the fellows/runtimes repository
