Fix problems with navigation events that aren't generated by GtkWebKit.

Fix problems with navigation events that aren't generated by GtkWebKit.
(used lib: libwebkit2gtk-4.1-0 on linux Mint).

The WebKit engine to apparently doesn't catch the navigations and does not produce navigation events, when something like "webui_bind(_webui_win, "", webui_event_handler);" is called. Although this should be expected behaviour.

By implementing a handler for the GtkWebKit decision signal, this navigation event can still be generated.

Yes, this is a Windows workflow fails to find TLS, this because GitHub added Windows Server 2025. I will try to fix it.

@hdijkema I noticed that catching events now have two different functions, one is the regular webui_bind() with empty string, and the other ones are those added in your recent PRs. To not force all wrappers to be updated, and to not force to update all documentation, I will try to redirect those WebView event to the regular one, so no wrappers and documentation will need to be updated.

I'm curious how you want to do that. Oh I see. You can of course catch this in the regulare webui_bind() with an empty string. Great. good Idea I think.

I will use your own GTK code to catch event and sends it to webui_bind(), then will be blocked by default. Then user can use webui_navigate() API to perform the navigation. The goal is the same exact code that work for web browser should work also for WebView.
