We don't need the bodyName member, because it's the same as
originalBodyName, just encoded, and we can delay the encoding to
build() time.
This is not worse than the old code, since we anyway toString() the
QAnyStringView unconditionally.
So we don't need to visit the QASV and implement RFC2232 encoding for
all three view types, we can just use the QString version, after
toString().
This not only has the advantage of less code and not storing duplicate
data, but we now also encode u8"ä.txt" the same as "ä.txt"_L1 and
u"ä.txt", ie. using latin1, as required by Postel's Law, and not as
UTF-8, as the old code did.
