Turn tests green, for a short while, maybe (#37218)

## [Rewrite `BackgroundMusicManager` to not run into framework breakage](https://github.com/ppy/osu/commit/622216d8911832c39fa4e126b2810e4e0f46cbf7) The attempted proper fix to this was https://github.com/ppy/osu-framework/pull/6727. Unfortunately when presented with [the framework bump](https://github.com/ppy/osu/pull/37217) with that change, CI says "you're stupid" and fails on some disposal idiocy that of course is undebuggable and irreproducible: The active test run was aborted. Reason: Test host process crashed : Unhandled exception. System.AggregateException: One or more errors occurred. (Object reference not set to an instance of an object.) ---> System.NullReferenceException: Object reference not set to an instance of an object. at osu.Framework.Audio.Sample.SampleChannelBass.Dispose(Boolean disposing) at System.Threading.ExecutionContext.RunInternal(ExecutionContext executionContext, ContextCallback callback, Object state) --- End of stack trace from previous location --- at System.Threading.ExecutionContext.RunInternal(ExecutionContext executionContext, ContextCallback callback, Object state) at System.Threading.Tasks.Task.ExecuteWithThreadLocal(Task& currentTaskSlot, Thread threadPoolThread) --- End of inner exception stack trace --- at osu.Framework.Audio.AudioCollectionManager`1.UpdateChildren() at osu.Framework.Audio.AudioCollectionManager`1.UpdateChildren() at osu.Framework.Audio.AudioCollectionManager`1.UpdateChildren() at osu.Framework.Audio.AudioCollectionManager`1.UpdateChildren() at osu.Framework.Threading.AudioThread.OnExit() at osu.Framework.Threading.GameThread.setExitState(GameThreadState exitState) at osu.Framework.Threading.GameThread.RunSingleFrame() at osu.Framework.Threading.GameThread.<createThread>g__runWork|70_0() at System.Threading.ExecutionContext.RunInternal(ExecutionContext executionContext, ContextCallback callback, Object state) --- End of stack trace from previous location --- at System.Threading.ExecutionContext.RunInternal(ExecutionContext executionContext, ContextCallback callback, Object state) (https://github.com/ppy/osu/actions/runs/24019928154/job/70046733058?pr=37217#step:5:119) I no longer have the energy for any of this shit. @nekodex would appreciate if you could check that I actually haven't broken anything with the bgm here. Seems okay to me in test scenes at least. ## [Apply lowest-effort maybe-fixing changes to a bunch of flaking tests](https://github.com/ppy/osu/commit/7bd3ca4adfcce5b90add11565a13f3fe9177ad5e) None of the failures are reproducible locally, of course. I'm tired of this. If anyone else wants to subject themselves to actually investigating any of these, by all means, godspeed and good luck.
