Update the compiler on Windows to Visual Studio 2022 17.5.0. This provides the needed C++20 support for the next WebKit update.

On Windows, the existing WebKit 615.1 build fails with Visual Studio 2022 17.5.0 -- see [JDK-8303748](https://bugs.openjdk.org/browse/JDK-8303748). The solution for the failure is to compile 615.1 using the C++20 flag for Windows (we will use this flag on all platforms for the next WebKit update). The fix for that bug is necessarily included in this PR, since the two fixes as interdependent.
