Add null backendjellyfish_9.99.4jellyfish/9.99.49.99.4

Changes:
- Add null radio implementation that acts as the fallthrough default
  when the hardware implementations are not detected.
- Tweaked the probing in the tef665x implementation to not return an
  error if the I2C node is not even present. This cleans up the logs
  on start up on most platforms. These changes include some minor
  whitespace consistency clean ups.
- Added the run-by-default widget permission now that the binding
  should always work. This will ease testing, and potentially decrease
  app start up time.
