QMetaObject: port QArgumentType to QByteArrayViewHEADdev

Now that argumentTypesFromString() actually doesn't normalize types
anymore, all type names are substrings of the signature, and so
QByteArrayView suffices (was: QByteArray) to hold the result.

QArgumentType in only used transitively, during QMetaObject member
function or QObject::connect() calls, so the source string will also
never go out of scope before the QArgumentType object that references
it.

As a drive-by, make the QArgumentType ctor explicit and port from
QVLA::op+=() to emplace_back().

No discernable impact on tst_bench_qobject's connect_disconnect.
