Pull request overview
This PR implements the WebResourceRequested event and filtering functionality for WebView2 across multiple platforms (Android, iOS, macOS, WASM, Windows). This feature allows applications to intercept and modify HTTP requests made by the WebView, enabling scenarios like custom header injection and request/response modification.
Key changes include:
- Cross-platform implementations with varying capabilities due to underlying platform WebView limitations
- JavaScript-based interception for iOS/macOS to inject headers into fetch/XMLHttpRequest calls
- Request re-fetching mechanism for Android with cookie synchronization
- Comprehensive event args, request, response, and header management classes

…tibility - CoreWebView2: Match parameter name 'ResourceContext' (uppercase R) - CoreWebView2HttpRequestHeaders: Remove 'virtual' keyword to match non-virtual stubs No PackageDiffIgnore entries needed - signatures now match exactly.

src/Uno.UI/UI/Xaml/Controls/WebView/Native/Wasm/NativeCoreWebView2HttpRequestHeaders.wasm.cs:124
NativeCoreWebView2HttpRequestHeaders.wasm.csdeclaresNativeCoreWebView2HttpRequestHeadersunconditionally (no#if __WASM__ || WASM_SKIAguard), while Android and iOS/macOS define the same partial class in platform-guarded files. On Android/iOS builds this will result in duplicate member definitions for the same partial type and likely compilation errors. Please add the appropriate platform conditional (#if __WASM__ || WASM_SKIA/#endif) around this file’s implementation so that it is only compiled for the WASM targets, consistent with the other*.wasm.csfiles.
