Add support for address hiding [1/3]

- Add an interface IRedactedLoggable
- Add ToStringForLogging and ToRedactedStringForLogging to address classes
  - RawAddress and tBLE_BD_ADDR do not implement ILoggable
    Some existing code relies on the size of these structs
  - hci::Address and hci::AddressWithType implement ILoggable
  - unit tests

Test: atest bluetooth_test_gd_unit net_test_types
