bluetooth/shell: Extend the shell output of scan data that can be toggled

[demantmrrv]

Currently we get a balanced amount of output in the shell when scanning, which applies to general usage when scanning for some or all devices. However, when testing more advanced advertising features of a device, especially extended advertising and LE-Audio, outputting more (or all) received data in an ordered format is desirable.

The feature can be toggled on and off (default) and will add a considerable amount of extra output. Hence, it should preferably be used in conjunction with the scan filter.
This enhancement can be done by adding extra checks and formatting in subsys/bluetooth/shell/bt.c and should not impact current implementation.
