REGRESSION (Safari 26): AudioData.copyTo() crashes the tab with valid
conversion
https://bugs.webkit.org/show_bug.cgi?id=302521
rdar://164730320
Reviewed by Jean-Yves Avenard.
The RELEASE_ASSERT in PlatformRawAudioDataCocoa::copyTo() required
(increment - 2) more elements than necessary. This caused crashes
when copying planeIndex 2 from 3-channel AudioData.
