EPA: Remove [AddEpAnn] Commit 4

EPA: Remove [AddEpAnn] from DataDecl

This is quite a big change.
The most important part is moving the annotations into HsDataDefn,
using a specific annotation data type.

It has a knock-on to everything that uses HsDataDefn

EPA: Remove [AddEpAnn] for FunDep

EPA: Remove [AddEpann] from FamilyDecl

EPA: Remove [AddEpAnn] From InjectivityAnn

EPA: Remove [AddEpAnn] from DefaultDecl

EPA: Remove [AddEpAnn] from RuleDecls

EPA: Remove [AddEpAnn] from Warnings
