Create the DWriteCore asset. DWriteCore is now part of the WindowsAppSDK
which is distrubuted as a nuget package. To update, go to
https://www.nuget.org/packages/Microsoft.WindowsAppSDK and pick a version.
The URL below should match that of the "Download package" link.
 
The asset this creates contains just the DWriteCore headers and dll. In
particular the lib is not bundled as Skia does not link directly against
DWriteCore.
