split kusama/polkadot runtimes

[brenzi]

reasons:

• for now, we'll keep sudo on polkadot (until bridge is publicly enabled)
• relay location needs to be hard-coded for proper XCM setup

checks

• state migrations are complete for polkadot too (v43 to v550). including collator-selection
• chopsticks runtime upgrade.
  • npx @acala-network/chopsticks@latest --config ~/chopsticks/configs/integritee-polkadot.yml --wasm-override ~/integritee/bin/1.13.2-v550-polkadot/integritee_polkadot_runtime.compact.compressed.wasm
  • collator set ok
  • tx works
  • spec version: 550
  • try again with new runtime spec_name
    • Events are not shown in Network view, but execution is complete
• double-check SE: https://substrate.stackexchange.com/questions/12047/what-to-consider-when-changing-a-parachains-spec-name
• test upgrade on paseo ( use integritee-kusama)
  • does the spec_name change lead to any trouble?
• re-enable spec version check in migrations CI

disclaimer

• this change is only really complete for runtimes. generation of genesis specs is not updated and will still default to integritee-kusama. However, we should deprecate our own client in favor of omni-node anyway

Only some tiny questions, looks good otherwise.
