Add otPlatRadioGetReceiveSensitivity() API (#1715)

Browse Source 
* Add otPlatRadioGetReceiveSensitivity() API

* Add a new otPlatRadioGetReceiveSensitivity() API to get sensitivity value;

* Use the receive sensitivity value as the noise floor for link metric computation;

* Remove some unused noise floor related functions.

* Add SPINEL_PROP_PHY_RX_SENSITIVITY Spinel/NCP property
