Add tests for Audio module types

[ChrisThrasher]

Description

This will remain a draft PR until #2749 is merged as to avoid introducing more merge conflicts into that PR.

I first wrote these tests a long time ago but just realized that we can use the trick as we do for the tests that require a display. Only the macOS jobs include an audio device so that's the only OS on which we can run these tests. Not great but better than nothing. These tests should still pass on everyone's own development machine since we all use computers with sound cards.

Coverage of these Audio module types is not perfect but we can improve that later once this first tranche of tests is merged.

For some reason after adding new sf::Music tests that load sounds from disk, the tests now hang indefinitely on our Arm Mac runners. On my own Arm Mac these tests work perfectly fine completing in <2 seconds. I'd guess there is some difference in hardware between the macOS 12 x86 runners and the macOS 14 Arm runners that is causing this. Not sure how to go about debugging this since I can't reproduce it locally.

I'm marking this as ready for review because these tests catch a bug in the current implementation of #2749 and detect some minor behavior changes. I think it's worth merging these tests first so that the Miniaudio PR can benefit from some better automated testing.

With the changes from #2966 I was able to enable the audio tests on Windows as well! This PR is ready to merge once the BuildBot is updated to set -DSFML_RUN_AUDIO_DEVICE_TESTS=OFF for the jobs that are currently failing. Those machines much lack the hardware required to run these tests just like GitHub's Linux runners lack such hardware.
