Remove v0 parachains runtime (#1501)

* remove v0 parachains modules and switch to v1 primitives

* get tests compiling for runtime-common

* remove registrar module

* Add a dummy module

* remove runtime-parachains

* mostly remove old parachains code from polkadot-runtime

* remove slots::Trait implementation

* remove sp_std prelude import

* add a ZeroSizedTypeDifferentiator to dummy

* finish porting over polkadot runtime

* ZeroSizedTypeDifferentiator was actually unnecessary

* westend

* kusama

* test-runtime (no dummy modules)

* fix warning

* fix chain-specs

* fix test-service

* test-client

* remove dead import

* remove unused needed_extrinsics parameter

* runtimes compile

* remove rococo-v0

* remove remaining references to Rococo

* bump versions
