This function was not appearing in the QVariant docs because the \fn command
was wrong and because clang was not seeing the declaration in qvariant.h in
the first place. With this update, the function does appear in the docs, but
it's signature is not correct because clang can't find a definition for
std::variant<Types...>, which probably means it doesn't have the most recent
declarations in the std namespace.

Some old uses of Q_QDOC to prevent the old qdoc C++ parser
from seeing declarations it didn't need to see were preventing
clang from seeing declarations it did need to see. These have
been removed, and some internal documentation has been added to
account for some declarations that suddenly became public but
should not be seen in the Qt API.

As it were, QStringLists were not handled explicitly when comparing
QVariants. If both QStringLists contained only a single entry, they
were treated as QStrings - if both QStringLists were empty, there were
equal (correctly so) - but if one of the QStringLists had more than
one entry, the compare function fell through to returning always 1.

QVariant::canConvert<Enum> was returning true for everything can can be converted
to integer, but not for integer itself. That's because in QVariant::canConvert
we set the targetType to Int of it's an enum, but the Int->Int case was not
on the conversion matrix. So this commits adds it to the conversion matrix
and now QVariant::canConvert<Enum> returns consistently true for int itself.
But even tough canConvert returned true, it did not actualy do any conversion
to the enum type itself. Fix that by handling the case properlt in 'convert'
