Disabling BaseAudioContextAutoplayTest on all platforms

The test has been flaky and we could not reproduce the time-out locally.
To suppress the warning/error, we should disable the test until
we figure out the solution.

BaseAudioContextTest: attempt to fix disabled tests.

Re-enabling the tests as they pass locally and pass in dry run.
If they are still failing, it will allow to look at logs.

Is is removing the code specific to AudioWorklet thread as it was
breaking the tests and it is not needed.
