Move types from GHC.Types.Basic to L.H.S.*

This cuts a few different edges between L.H.S and GHC.Types.Basic

* RuleName is moved to L.H.S.Basic
* fdTopLevel (TopLevelFlag) has been moved to the extension field of FamilyDecl
* OverlapMode has been moved to L.H.S.OverlapPragma
  * SourceText has been moved to its extension fields
  * NonCanonical has been moved to its extension constructor
* InlinePragma has been moved to L.H.S.InlinePragma
  * SourceText and Arity have been moved to its extension point
  * Activation and InlineSpec have also been moved to L.H.S.InlinePragma
* And some general churn as functions and instances move to new locations
  * GHC.Hs.OverlapPragma contains ghc specifics for L.H.S.OverlapPragma and
  * GHC.Hs.InlinePragma contains ghc specifics for L.H.S.InlinePragma
  * TyConFlavour definition is moved to GHC.Hs.Basic to avoid cyclical dependency
