By monitoring the objectCreated() signal of QQmlApplicationEngine we can
also catch errors if the components are instantiated asynchronously.

This reverts commit dcb8681cb7.
The effort to handle asynchronous loading is not required for the
qmllivepreview (for which it had been introduced).

Avoid setting Qt::AA_EnableHighDpiScaling when running in the simulator.
Simulator detection is done by testing whether environment variable
QTGLESSTREAM_DISPLAY is set.
This amends 8c3bd61594 where all platforms
except Windows were excluded from setting the flag.

Setting Qt::AA_EnableHighDpiScaling causes a few graphics backends to
malfunction. This patch reduced the setting of the flag to happen only
on Windows (it is automatically set on macOS with retina).

There are a number of reasons why the root component of a QtQuick
application may be loaded asynchronously. It might, for example, be
derived from a component loaded over the network.
In that case, checking that there is a root object right after calling
load() is misleading. The object is only created later. Therefore, we
need to listen for the objectCreated signal to decide if the root
component was correctly created.
As calling qApp->exit(-1) does nothing while the event loop isn't
running, we always connect the check with Qt::QueuedConnection.

It now really creates an empty project.

When something goes wrong with deployment or there is a syntax
error in the QML files, the old code would enter the main
loop not showing any windows. Worse, the binary is then locked
on Windows and cannot be overwritten. Add a clause checking
whether there are any root objects and bail out on failure.
