The documentation was previously code-heavy and short on exposition,
while focusing almost entirely on the CBOR converters. Prune most of
the CBOR code quotes, shuffle some snippet markers, add and remove
others and rewrite the main text.
Shift focus to the base-class for converters and how it's used by
main(). Retain relative focus on the CBOR converters, as they are
relatively full-featured hence illustrate more than the others do, and
replace the sequence of single-line sections about the others with a
section collecting all into a table and saying some general things
about them.

The Out-only converters shouldn't need to implement loadFile(), as it
shouldn't be called - a converter is not used for input unless it says
it supports input. At the same time, provide the "ground state"
implementations for optionsHelp(), outputOptions() and probeFile() to
save the trivial implementations the need to duplicate one another.
In the process, make the handling of loadFile()'s outputConverter more
consistent among those that do implement it. Always set
outputConverter if it's initially null (the caller does assert this).

Mostly to pave the way for moving the class code to a file of its own,

Moving the underlying object to a local static of a private method

The Converter class, in the eponymous example, had a null member
variable that wasn't a nullptr - it pointed to an instance of
NullConverter - so that other converters could test whether a
Converter * they'd been passed was null (in the sense of pointing to a
NullConverter). This, however, was susceptible to misreading - I
misread one such comparison as a nullptr check and thus thought it
redundant with an earlier actual nullptr check. To spare future
readers similar confusion, replace the public static member variable
with a protected (since only other derived classes need it) static
predicate, to at least give the reader a clue that this is using the
word null in a class-specific sense.

The extra code for using the OpenGL paint engine is significant enough
to be distracting from what the examples are supposed to show. If we
want to show how to use QPainter on an OpenGL widget, then we can make
dedicated and documented examples for that, in the OpenGL category. And
we have such examples in the Qt OpenGL module anyway.
As is, the examples feel more like manual tests of the OpenGL paint
engine; if we need more coverage there, then we can add it there.

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
