Re-add PlatformCheck to CefSharp.Common.targets - as AnyCPU won't work out of the box we'll still advise to use x86/x64, to use AnyCPU you'll need to

set CefSharpAnyCpuSupport in your project before you'll be allowed to use it, should hopefully reduce all the support complaints for those
who don't read the documentation.
