These are builders that were migrated from json to Chromium recipe
configs, e.g. crrev.com/c/2071293, before Week 1b could be relanded.

This group of builders is to migrate those builders separately:
- ios-simulator-cr-recipe (inactive since Nov 2019)
- ios-simulator-cronet
- ios-webkit-tot
- ios13-sdk-device

Schedule of migration:
