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

from the radio. This value can be used in energy scans and for
determining the ambient noise floor for the operating environment.
### PROP 39: PROP_PHY_RX_SENSITIVITY {#prop-phy-rx-sensitivity}
* Type: Read-Only
* Packed-Encoding: `c` (int8)
* Unit: dBm
Value is the radio receive sensitivity. This value can be used as
lower bound noise floor for link metrics computation.
