New measure for graphics driver evaluations

To monitor the overall health & reliability of Windows Machine learning feature, we have developed a new measure that provide a view into the health of graphics drivers on machines using Windows Machine Learning.

1. Percent of Device with WinML Runtime Error (https://docs.microsoft.com/en-us/windows-hardware/drivers/dashboard/pct-devices-winml-runtime-error) looks at devices using Windows Machine Learning that have reported a WInML runtime error

This measure is currently being evaluated and will be used to make accept/reject decisions starting June 5, 2020.
