Adding details to human readable audio route names

This name will be displayed in the quick settings tile on TV devices and
having it match more closely with the will create a better user experience.

Routes that were added more recently didn't have their own names, using
external device instead. The product="TV" tag was not working leading to
'Phone' labels in the TV UI.

Bug: 407548532
Test: manual - switch between different outputs on TV and check
dashboard quick settings tile subtitle
