Bluetooth: Use extended scanning if controller supports
This implements Set extended scan param and set extended scan enable
commands and use it for start LE scan based on controller support.
The new features added in these commands are setting of new PHY for
scanning and setting of scan duration. Both features are disabled
for now, meaning only 1M PHY is set and scan duration is set to 0
which means that scanning will be done untill scan disable is called.
