Separate ParachainId injection to its own pallet (#183)

* Separate paraid injection to own pallet

* Move token dealer to a crate

* Move to rococo-parachains

* Remove parameter_types hack

* Fix chainspec

* fix build

* remove commented code

* Update contracts runtime to match other runtime

* Apply suggestions from code review

Co-authored-by: Bastian Köcher <bkchr@users.noreply.github.com>

* Alphebetize workspace members

* Parachain info to own crate

* prune system = frame_system
