• Add disable kcef flag to disable kcef webview for platforms which don't support it #1856

This PR makes it possible for 3rd party webview's can be used. This is required for mobile as kcef isn't supported on iOS or Android.

With this PR and my other one I can support webviews on mobile 🥳

This PR can be tested with
