In preparation for Qt 6 deprecating the binary JSON format. Also reduces
the size of the metadata a little: for the xcb platform plugin, it went
down from 264 bytes to 138; for the jpeg image plugin, it went from 320
to 135.
I've had to change the signature so older versions of Qt won't try to
parse the CBOR data as Binary JSON. Unfortunately, before QJsonDocument
could get a chance to reject it, qJsonFromRawLibraryMetaData() needed to
allocate memory and that causes crashes with Qt < 5.11.2.

Eight bytes into the Binary JSON header there's a 32-bit little-endian
size, which qJsonFromRawLibraryMetaData uses to determine the size of
the stored metadata. That value is passed as a size to QByteArray, which
means certain values could cause crashes due to being too big or via
sign-extension in 64-bit.

crash when certain damaged or corrupt plugin files were scanned.

For the windows file system engine, we add an extra macro to use
library loading if configured to do so, but avoid it on WinRT, as
none of the symbols would be found.
We also QT_REQUIRE_CONFIG(library) in the library headers and
exclude the sources from the build if library loading is disabled.
This, in turn, makes it necessary to clean up some header inclusions.

QPluginLoader hasn't unloaded in its destructor since Qt 5.0, but we
missed the equivalent code in QFactoryLoader (which bypasses
QPluginLoader). Besides, QPluginLoader::unload() was still doing
unloading, which it won't anymore.
Not unloading plugins is Qt's policy, as decided during the 5.0
development process and reaffirmed now in 5.6. This is due to static
data in plugins leaking out and remaining in use past the unloading of
the plugin, causing crashes.
This does not affect QLibrary and QLibrary::unload(). Those are meant
for non-Qt loadable modules, so unloading them may be safe.

We keep two symbols from QPluginLoader defined, even if QT_NO_LIBRARY
is set in order to be able to locate static plugins. This doesn't
constitute any loading of shared libraries or plugins from external
files at runtime.
Using these symbols we can enable most of QFactoryLoader even if
QT_NO_LIBRARY is set. Only update(), refreshAll(), library() and
the dtor make no sense then. This way QGenericPlugin also becomes
useful with QT_NO_LIBRARY.

Currently there is no API to extract the meta data

QLibraryPrivate into QPluginLoader, and makes it public.
As such, we now also export QStaticPlugin.
Since an application developer cannot do much with raw
metadata, we add a new function
QStaticPlugin::metaData() that returns the QJsonObject
for the plugin. The old metaData function is
renamed 'rawMetaData'.
