Replace the ad-hoc implementation of QTest::toString() in
tst_qglobal.cpp with a QDebug stream operator, so the
QTest::toString() fall-back to QDebug::toString() kicks in.
Since the ABI issues revolving around the new int128 types are not
known, yet, avoid baking the types into the ABI by a) making the
operators constrained templates¹ and b) passing though void* to the
exported helpers. These functions return an error message if Qt was
compiled without support for int128.
Use the Thiago Trick™ (leaving obviouly dead code around for the
compiler to remove without warning) to expose more code to more
compilers. This appears to work elsewhere in Qt, so I hope it does
here, too.
This completes the minimum qint128 support so we're able to debug code
and write tests that use these types.
¹ Templates, unlike inline member functions of wholly-exported
classes, never² become part of the ABI.
² <insert here the convoluted scenario under which this is false>

The whole Q_DECLARE_METATYPE part is superfluous in these two examples,
as QVariant works with any type as long as it is copy-constructible.
And QVariant will call the equivalent of qRegisterMetaType, so that
doesn't need to happen, either.
Showing how to integrate the type with qDebug is fine in theory, but
also a repetition of content that can be found in other places.
Given that there isn't much else being shown in these two examples, it's
better to remove them from examples and move them to manual tests.
Some parts of "Custom Type Example" were used as snippets in other
documentations under qtbase/src/corelib. So, they were added in
