PTS-bot: global configuration

- Change PTS-bot configuration to match the Android Bluetooth
  stack ICS. Enabling new tests can be done by modifying the
  PtsBotTest.xml TF configuration file.
- Update skipped tests to match with what is currently implemented.
- Add a `pass` field to PTS-bot configuration file to provide
  visibility on the tests which are already implementing and must
  pass. This field is purely indicative and is not being used by
  PTS-bot itself. Note: AVDTP/SRC tests are not yet enabled because
  there is a current issue when running them all sequentially.
