[BlazorWebView] Implement web request interception

[mattleibow]

Description of Change

This is the same work as #28876, but for BlazorWebView.

This pull request introduces support for intercepting and handling web resource requests across multiple platforms in the Blazor WebView framework. The primary changes include adding new event hooks for request interception, enhancing logging for debugging purposes, and refactoring existing classes to support the new functionality. Below is a summary of the most significant changes, grouped by theme:

Web Resource Interception and Event Handling

• Added a new WebResourceRequested event to the BlazorWebView and HybridWebView components, allowing applications to intercept web resource requests and provide custom responses. This includes setting the Handled property and invoking appropriate methods to define the response. (src/BlazorWebView/src/Maui/BlazorWebView.cs [1] [2]; src/Controls/src/Core/HybridWebView/HybridWebView.cs [3]

• Updated the IBlazorWebView interface to inherit from IWebRequestInterceptingWebView, enabling web resource interception as part of the Blazor WebView contract. (src/BlazorWebView/src/Maui/IBlazorWebView.cs src/BlazorWebView/src/Maui/IBlazorWebView.csL11-R11)

Logging Enhancements

• Introduced detailed logging in the web resource interception flow to aid debugging. Log messages are added to indicate when requests are intercepted, handled, or passed through unmodified. (src/BlazorWebView/src/Maui/Android/WebKitWebViewClient.cs [1] [2]; src/BlazorWebView/src/Maui/Windows/WinUIWebViewManager.cs [3] [4]; src/BlazorWebView/src/Maui/iOS/BlazorWebViewHandler.iOS.cs [5] [6]

Platform-Specific Web Resource Handling

• Implemented platform-specific logic for intercepting and handling web resource requests on Android, iOS, and Windows. This includes checking if requests should be overridden, handling Blazor-specific resources, and falling back to default behavior if necessary. (src/BlazorWebView/src/Maui/Android/WebKitWebViewClient.cs [1] [2]; src/BlazorWebView/src/Maui/Windows/WinUIWebViewManager.cs [3] [4]; src/BlazorWebView/src/Maui/iOS/BlazorWebViewHandler.iOS.cs [5] [6]

Refactoring and Renaming

• Renamed PlatformHybridWebViewWebResourceRequestedEventArgs to PlatformWebViewWebResourceRequestedEventArgs to generalize its usage and align with the new WebResourceRequested event. Updated all references accordingly. (src/Controls/src/Core/WebRequestInterceptingWebView/PlatformWebViewWebResourceRequestedEventArgs.cs [1] [2] [3] [4] [5] [6]

Miscellaneous

• Added missing namespace imports and minor adjustments to ensure compatibility with the new functionality. (src/BlazorWebView/src/Maui/Android/WebKitWebViewClient.cs [1]; src/BlazorWebView/src/Maui/BlazorWebView.cs [2]; src/BlazorWebView/src/Maui/iOS/BlazorWebViewHandler.iOS.cs [3]

These changes enhance the flexibility and extensibility of the Blazor WebView framework, enabling developers to customize how web resources are handled across different platforms.

Pull Request Overview

This PR implements web request interception for BlazorWebView by reusing the existing interception types from MAUI and updating various platform‐specific implementations. Key changes include making platform event argument constructors public, refactoring naming from HybridWebView to WebView, and extending web view interfaces to support request interception.

src/Core/src/Primitives/WebResourceRequestedEventArgs.cs:10

• Changing the accessibility of the constructor from 'internal' to 'public' in this platform-specific event args class is a breaking change. Please confirm that this change is intentional and documented.

public WebResourceRequestedEventArgs(global::Microsoft.Web.WebView2.Core.CoreWebView2 sender,

src/Core/src/Primitives/WebResourceRequestedEventArgs.cs:36

• Changing the constructor accessibility from 'internal' to 'public' for the iOS/MacCatalyst version represents a breaking API change. Please ensure this is clearly documented.

public WebResourceRequestedEventArgs(global::WebKit.WKWebView sender,

src/Core/src/Primitives/WebResourceRequestedEventArgs.cs:61

• Promoting the constructor from 'internal' to 'public' for the Android platform is a breaking change. Please verify that the corresponding documentation and clients are updated accordingly.

public WebResourceRequestedEventArgs(global::Android.Webkit.WebView sender,

src/Core/src/Core/IHybridWebView.cs:8

• Extending IHybridWebView to implement IWebRequestInterceptingWebView is a public API breaking change. Please ensure that this alteration is well documented for consumers of the API.

public interface IHybridWebView : IView, IWebRequestInterceptingWebView

src/BlazorWebView/src/Maui/IBlazorWebView.cs:11

• Having IBlazorWebView extend IWebRequestInterceptingWebView constitutes a breaking change in the public API. Please verify that any consumers are aware of this change.

public interface IBlazorWebView : IView, IWebRequestInterceptingWebView
