Improved readability of tests in master.cfg and enabling some tests

Focused responsibility of supported tests in master.cfg instead of being in utils.py (hard to overview and maintain).

Enabled the following empty tests on all platforms:
- audio_conference_mixer_unittests
- cng_unittests
- g711_unittests
- g722_unittests
- pcm16b_unittests
- media_file_unittests
- udp_transport_unittests
- webrtc_utility_unittests

Removed "headless tests" concept since everything is now compiled in the make all step (no need for compile only, no execution tests).
Removed audio_device_test_func test since not a proper test (dev tool) that was configured as headless.

BUG=
TEST=Ran local master and successfully built and executed all tests with Mac build slave.
