[11u] RFR: 8236500: Windows ucrt.dll should be looked up in versioned WINSDK subdirectory

[Langer, Christoph]

Hi,

please review a backport of a carveout of JDK-8215445: "Enable building for Windows in WSL" [0]. When building 11u after I've reinstalled Visual Studio and the Windows Devkit to non-default folder locations, I ran into the issue that ucrt.dll would not be correctly resolved, since it sits in a versioned subdirectory of ...\WindowsKits, e.g. ...\WindowsKits\10\Lib\10.0.17763.0\ucrt\. This problem was fixed as part of JDK-8215445. However, I don't want to backport the whole change, at least not at the moment, so I created a new bug to fix this specific issue in OpenJDK 11 Updates. Please review.
