Rococo & Westend People Chain (#2281)

Rococo and Westend runtimes for the "People Chain". This chain contains the Identity pallet with plans to migrate all related data from the Relay Chain. Changes `IdentityInfo` to: - Remove `additional_fields`. - Add `github` and `discord` as first class fields. From scraping chain data, these were the only two additional fields used (for the Fellowship and Ambassador Program, respectively). - Rename `riot` to `matrix`. Note: This will use the script in https://github.com/paritytech/polkadot-sdk/pull/2025 to generate the genesis state. TODO: - [x] https://github.com/paritytech/polkadot-sdk/pull/1814 and integration of the Identity Migrator pallet for migration. - [x] Tests: https://github.com/paritytech/polkadot-sdk/pull/2373 --------- Co-authored-by: Muharem <ismailov.m.h@gmail.com> Co-authored-by: Michal Kucharczyk <1728078+michalkucharczyk@users.noreply.github.com> Co-authored-by: Dónal Murray <donal.murray@parity.io> Co-authored-by: Richard Melkonian <35300528+0xmovses@users.noreply.github.com> Co-authored-by: Liam Aharon <liam.aharon@hotmail.com>
