Fix for different per-monitor scaling (#657)
* Use DPIAware::DEFAULT_DPI

* Make runner DPI-unaware, since it doesn't need to use a Per Monitor V2 DPI.

* Programmatically enable "Per Monitor V2 DPI" for the runner proccess and use a separate DPI-unaware thread for the corresponding API calls

* Increase PCH memory limit for settings project

* Address review issues

* Draw zoneWindows properly scaled
