Add unused volatile pointers to the type registration functions in each
import plugin. We need to do this in order to prevent the linker from
optimizing the registration away. There are two ways for this to happen:
When linking statically, the linker will examine the referenced symbols
on a per-object base and leave out all unreferenced objects. When
linking dynamically, the linker may do the same on a per-library base
and drop any unreferenced libraries from the dependencies. Forcing a
reference to the type registration function prevents both.
The volatile technique allows us to remove the previous qCDebug() hack.
Having an unused volatile auto variable should only result in a single
memory read as runtime overhead. The qCDebug() technique would generate
a read and a block of mostly dead code (as no one would ever use that
logging category).
Fixes: QTBUG-81622

Now that we can generate all QML type information at build time, we
should also use it.
Move the types for QtTest into the testlib import plugin. They don't
need to be exported from QtQuickTest.
Trigger the resource initialization of the shapes library from the
plugin so that we retain a dependency and the linker doesn't optimize
the module initialization away.

From now on we prefer nullptr instead of 0 to clarify cases where
we are assigning or testing a pointer rather than a numeric zero.
Also, replaced cases where 0 was passed as Qt::KeyboardModifiers
with Qt::NoModifier (clang-tidy replaced them with nullptr, which
waas wrong, so it was just as well to make the tests more readable
rather than to revert those lines).

When the new shared memory image provider was added, some of the
issues identified during review were postponed to be fixed during
stabilization phase. This commit deals with
- Replace the kludge for registering plugin version
- Add autotest
- Place plugin in labs
- Use QT_CONFIG instead of QT_NO_xxx
- Use the new extended image provider api, in order to use the
scaled-size calculation from Quick

Adds functionality to save CPU memory when several processes use the
same local image files.
Example and autotest will be added during stabilization.
