Bug 1719923 [wpt PR 29629] - Add AudioData::copyTo(), a=testonly
Automatic update from web-platform-tests Add AudioData::copyTo() This CL updates AudioData according to the latest WebCodecs spec. It adds an allocationSize() and a copyTo() method to AudioData. WPTs will be included in future CLs, when AudioDataInit is updated to use a BufferSource instead of an AudioBuffer.
