Share code between AudioDestinationIOS and AudioDestinationMac
https://bugs.webkit.org/show_bug.cgi?id=203047
<rdar://problem/56340866>

Reviewed by Eric Carlson.

Source/WebCore:

Introduce AudioDestinationCocoa to share code between iOS and Mac.
Most code is now shared, except for the configuration of the audio unit which is slightly different between Mac and iOS.

Introduce MockAudioDestinationCocoa to allow more code coverage of the shared code.
This could also allow us to validate dynamic changes in frame rate, number of frames to process...
Add Internals API to enable the mock destination.

Covered by added test.
