tests bsim: Add simple tests for broadcast audio source/sink samples

Browse source 
Add an initial test based on the broadcast audio source/sink samples
which runs them together and after waiting for a predefined
amount of time, checks how many audio packets has the
sink received, and if over a threshold, passes the test.

This test can be expanded after to cover more functionality from
these samples.
