Avoid painting errors with dpr < 1, also for the PassThrough
mode.
This limits the minimum high-dpi scale factor to 1,
for the code path which determines the scale factor
based on screen DPI.

Initialize the offscreen platform plugin with no screens,
create QGuiApplication object.
Not much of the high-dpi related Qt API can be used
in this configuration, but at least Qt should not crash
on startup.

Android and Wasm do not build the offscreen platform
plugin (see src/plugins/platforms/CMakeLists.txt).
Skip building the tst_qhighdpi test as well in this
case. Remove the BLACKLIST entry.

Remove the qmake project files for most of Qt.
Leave the qmake project files for examples, because we still test those
in the CI to ensure qmake does not regress.
Also leave the qmake project files for utils and other minor parts that
lack CMake project files.

Use the new screen config feature of the offscreen
platform plugin to run tests on virtual screen setup.
This has the benefit that we can auto-test the QHighDpiScaling
implementation (as well as its usage in QtGui) on any platform
with a fixed mock screen setup which does not rely on physical
screen configuration.
Test the following configurations:
- three screens: 96 DPI. (reference)
- three screens: 192 DPI
- three screens: mixed (high) DPI
