The return value of this function is constant and some users call this function often (an earlier version of QGenericItemModel did, possibly QML does?), so memoize the result of the function instead of re-creating the QHash on every call. Use QAbstractItemModelPrivate::defaultRoleNames() so we don't need an instance to get the base class' contents. Add a comment to keep the two in sync. As a drive-by, port from the QByteArrayLiteral macro to _ba UDLs. Amends 32b586864e3a4398da38c045f4ac0823c3dc3c57.
