[MacOS] Set kAudioOutputUnitProperty_CurrentDevice on CoreAudioSharedUnit outputBus
https://bugs.webkit.org/show_bug.cgi?id=235632
<rdar://87771490>

Reviewed by Eric Carlson.

When VPIO is used for rendering audio, it is not always updating the audio route when system default speaker is updated.
While it is doing so when capturing using the built-in microphone, it is not doing so with BT microphones.

To make it reliable, we are now setting kAudioOutputUnitProperty_CurrentDevice on the output bus to the default output device.
Whenever we detect a change of default output device, we reconfigure the audio unit to select the new default output device.

Manually tested.
