macOS: Don't mangle QByteArray settings with @ prefix by decoding as UTF-8
QSettings encodes QVariants as @Type(data) strings. If that data contains
a null-byte, we write the string as UTF-8 encoded CFData. When reading it
back we look for a @ prefix, and then pass it as UTF-8 through stringToVariant.
The problem arises then the user writes raw QByteArrays with a @ prefix.
We can detect this situation by checking the result of stringToVariant,
and if it's just a simple conversion of the string into a QVariant, we
know that stringToVariant hit its fallback path due to not finding any
embedded variants.
If that's the case, we return the raw bytes as a QByteArray.
