Split up `GHC.Core` somewhatwip/rules-module

- `GHC.Core.Annotated` now contains annotated Core

- `GHC.Core.Rules` now contains the rules definitions

- `GHC.Core.Orphans` now contains the orphans *something*

- `GHC.Core.Unfoldings` now contains the unfoldings defintions

- The old `GHC.Core.Rules`, which was about applying rules, is now
  `GHC.Core.Rules.Apply`. Compare with `GHC.Core.Simplify.Inlin` which was also
  about operations not the data structures and simple predictes
  themselves (which is `GHC.Core.Unfold`).
