Migrate headers to support platform specializations

  Add plat_target.H, fapi2_target.H
  Add plat_error_scope.H, fapi2_error_scope.H
  Update documentation to reflect platform support
  Wrap buffer print() API to remove from platforms
  Move target operators to platform specific files
  Move target states to target_states.H
  Add plat_hw_access, fapi2_hw_access.H
  Make op mode and pib error platform specific
