Bluetooth: Add documentation to exported functions in lib

Browse Source 
Most functions in `net/bluetooth/lib.c` lack propper
documentation.

This patch adds documentation to all exported functions
in `net/bluetooth/lib.c`.
Unnecessary or redundant comments are also removed to
ensure the file looks clean.
