ethtool: Add new result codes for TDR diagnostics 

Add new result codes to support TDR diagnostics in preparation for
Open Alliance 1000BaseT1 TDR support:

- ETHTOOL_A_CABLE_RESULT_CODE_NOISE: TDR not possible due to high noise
  level.
- ETHTOOL_A_CABLE_RESULT_CODE_RESOLUTION_NOT_POSSIBLE: TDR resolution not
  possible / out of distance.
