WebAudio Mac expected results were misplaced - they apply equally to WK1 and WK2.
We didn't notice before because all these tests are disabled on WK1.

* platform/mac-wk2/webaudio: Removed.
* platform/mac/webaudio: Added.
* platform/mac/webaudio/audiobuffersource-playbackrate-expected.wav: Copied from LayoutTests/platform/mac-wk2/webaudio/audiobuffersource-playbackrate-expected.wav.
* platform/mac/webaudio/codec-tests: Copied from LayoutTests/platform/mac-wk2/webaudio/codec-tests.

* platform/mac-wk2/webaudio/audiobuffersource-loop-points-expected.wav: Removed.
This test is skipped, because it times out.

StyleResolver should deal in PassRef<RenderStyle> where possible.
<https://webkit.org/b/123061>

Make StyleResolver functions that returned or took RenderStyles
by PassRefPtr use PassRef instead where possible.
