[Testing] Feature matrix UITest Cases for WebView Control

[NafeelaNazhir]

This PR includes a comprehensive set of UI test cases for the WebView control. The tests validate the WebView control, including properties such as Source, CanGoBack, CanGoForward, events such as Navigating and Navigated Events, methods like GoBack, GoForward, EvaluateJavaScriptAsync and Reload.

WebView Feature Matrix :

• WebView Control Testing:

  • Added bindings for properties like Source, Cookies, and IsVisible, along with event handlers for Navigating, Navigated, and ProcessTerminated events. [1] [2]

• Navigation and Content Testing:

  • Implemented buttons and JavaScript to test navigation between pages, dynamic content updates, and JavaScript evaluation.

• Cookie Management:

  • Added functionality to add and clear cookies to test WebView's cookie handling capabilities.

Issues Identified

• [iOS] WebView.Reload() with HtmlWebViewSource returns WebNavigationResult.Failure in Navigated event #30515
• WebView GoBack/GoForward not working for HtmlWebViewSource on iOS #30381
