  ghc-internal: float Generics to top of module graph
  
  GHC.Internal.Generics currently exists in the middle of the ghc-internal module graph.
  It defines the Generics typeclass. Stuff below it gets an instance in GHC.Internal.Generics whereas stuff above it gets instances in their own modules.
  This splits the module graph in two and adds a lot of transitive dependencies to stuff above it.
  It also leads to a hs-boot loop via ByteOrder
  
  Resolves #26930
  
  Metric Decrease:
      T21839c
