Base commit to make QtSensors runnable on Windows

Fair amount of work remains after the commit still, but this should
allow further development as a compilable baseline: code compiles,
autotests pass, and most example applications at least start.

The changes:
-Change examples to use QtQuickControls 2 as per removal of v1
-Fix ambiguous conditional expression compilation error
-Link against runtimeobject library (previously part of winrt QPA?)
-Change the .pro file rule to win32 as winrt moniker does not exist anymore
-Remove references to deleted winrt event dispatcher
-Fix error handling: getdefault may be successful even if there is no default sensor
-Fix QCOMPARE failure output (toString has changed in Qt6)
-Remove qtimestamp alias which was deprecated already in Qt5
-Remove unit test hook that does not seem to be used anywhere
-From typedef to ‘using’ for readability
-Q_ENUMS -> Q_ENUM as the former has been obsoleted by the latter
-Add qt6 changes qdoc page
