moc: add lexem() functions that return QByteArrayViews
In many cases, the result of the lexem() functions is only used as a
view and is not stored. To avoid constructing thousands of temporary
QByteArray instances, introduce lexemView() and unquotedLexemView() that
return a QByteArrayView instead.
We need to carefuly remove .constData() calls on previously-QByteArrays,
because QByteArrayViews may not be NUL-terminated, so we must transfer
the size information to e.g. QString::fromLocal8bit().
This saves only about 3 % of temporary allocs but enables further
optimizations.
