Fix general Doxygen Documentation

- Ensure C++ namespace gets properly documented

-- Added tinyb namespace doc in BluetoothAdapter.hpp  (first file)

-- Added direct_bt namespace doc in ATTPDUTypes.hpp (first file)
   Showing hierarchy and hinting to details and coverage.

- Fix CMakeList for doc target and some doxygen config finetuning
