Add the Polkadot Coretime runtime (#410)

Add the Polkadot Coretime chain in advance of the 1.3.0 release. This uses the new Price adapter which has been running on Kusama now for two sales cycles, and includes the mechanism to burn revenue. TODO: - [x] Add Transact tests for hardcoded weights after #401 is merged - [ ] Rerun benchmarks and check hardcoded weights after merge The genesis chain-spec is developing on seadanda#4. This can be used as a merge target for any community boot nodes who would like to be included at genesis and will be separately merged to `main`. --------- Co-authored-by: Bastian Köcher <[email protected]> Co-authored-by: Branislav Kontur <[email protected]> Co-authored-by: fellowship-merge-bot[bot] <151052383+fellowship-merge-bot[bot]@users.noreply.github.com>
