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

(This code is required to handle corner cases such as a QWindow
covering multiple screens, where the normal code path does not
give correct results.)
Move the map[to|from]Global implementation from qhighdpiscaling.cpp,
and implement it in terms of [to|from]NativeGlobalPosition. These
functions implement the required screenAt()-type searching.
The implementation strategy for both mapping functions is to first
map to the native coordinate system, perform the globalPos addition
or subtraction, and then map the result back to device independent
coordinates.

If the maxSize argument is 0 (the default), QIODevice::readLine will
allocate a QByteArray with the size of the next chunk of data, which
may be quite large. Before returning, it then resizes the byte array
to the actual size that was read.
But since change 6b884d2aa1, QByteArray::resize() does no
longer shrink the capacity. This means that the returned QByteArray
keeps it's maximum size as allocated memory. This can lead to
excessive memory consumption, especially if the returned QByteArray's
are stored for further processing in the client code.
Fix this by explicitly calling QByteArray::squeeze() before returning.
