PPE FAPI2 resync changes

- Tested SCOMs (absolute and FAPI_TRY) on GPE SIMICS without RCs
  to chip target OCB registers.  GPE SIMICS model does not have
  registers in non-chip level targets.
- Testing on GPE SIMICS with RCs fails with illegal addresses in
  thread local storage initialization
- Added ./ppe/sbe/plat platform specifics
- Added missing ./ppe/hwpf/plat/include files
- Added missing fapi2AttributeService.H
- Add PPE specific (though likely temporary) versions of buffer.H
  (to deal with compile errors for "units_per_bit()" to "units_per_bit"
  and "bit_length()" to "bit_length") and return_code.H (to include
  return_code_defs.H)
- Add ppe/plat/include/plat_error_scope.H to deal with SBE return code
  tracing
- Deleted old file version
- Added local version of buffer.H
- Move current_err to global variable (vs thread local storage);
  This removes #include <thread>.
- Enable PK_TRACE under FAPI_* Trace macros
- Added plat_attributes.H to include generated platform specific files
- Added -DUSE_PK_APP_CFG to img_defs.mk
