js: represent QByteArray as JsArrayBuffer

On macOS, Info.plist can (rarely) contain binary data which is parsed
into a QByteArray. However, since byte arrays were discarded when
converting from variant, such keys were lost e.g. when doing plist
merging.

Fix that by converting QByteArray to a JS ArrayBuffer object.

Using such types is a bit awkward as seen in the testcase, but conforms
JS type system.
