tdf#35568 Repeat "first run" procedure on upgrade

1. In isProductVersionUpgraded, if it was upgraded, set FirstRun. This
will run in runGraphicsRenderTests, early enough in Desktop::Main().
2. This will make sure that Desktop::CheckFirstRun() will do its tasks,
including creation  of the quickstart shortcut.  It is simplified a
bit, to use a better WinAPI.
3. Setting FirstRun to false is moved to m_firstRunTimer's handler, to
make sure that it gets run eventually, even if the first launch was
terminated before the timer fired.

This will not make installer itself create the quickstart shortcut: it
will happen on the program's first run after an upgrade. But users now
won't have to enable the option manually each time.
