/**
* @brief set_thread_per_monitor_v2_awareness
*
* Qt <= 5.9 supports setting old (Windows 8.1) per-monitor DPI awareness
* via Qt:AA_EnableHighDpiScaling. We do this in main.cpp. In order for
* native dialogs to be rendered correctly we need to set per-monitor
* *v2* awareness prior to creating the dialog, which we can do here.
* Qt < 5.14(?) or so doesn't render correctly when per-monitor v2 awareness
* is enabled, so we need to revert our thread context when we're done.
* Qt >= 6.0 is per-monitor DPI awareness v2 by default, so this doesn't
* have any effect.
*
* @return The current thread DPI awareness context, which should
* be passed to revert_thread_per_monitor_v2_awareness.
