tests: Bluetooth: BAP: Modify BASE unittests to native_sim

Modify the unit tests to use the native_sim board instead of the
unit_testing board.
The native_sim board allows us to use the kernel in a more
regular way, while still being able to treat the tests as
unittest.

This commit also removes unused includes in the CMakelists.
