Fix crashes and assertions with AudioData.copyTo
https://bugs.webkit.org/show_bug.cgi?id=288440
rdar://145467725
Reviewed by Youenn Fablet.
When AudioData.copyTo() is executed, audioElementSpan() performs
spanReinterpretCast on the destination buffer but this crashes if the buffer
byte size is not a multiple of the byte size of the desired type.
