API Review: Trusted Origin APIs

[chetanpandey1266]

This pull request introduces a new specification for Trusted Origin support in WebView2, enabling applications to apply different security and feature policies based on the trust level of content origins. The changes provide APIs for designating trusted origins and configuring feature access and security settings per origin, addressing previous limitations around uniform policy enforcement.

Trusted Origin API and Feature Management:

• Added APIs to CoreWebView2Profile for creating, setting, and retrieving feature settings for trusted origins, allowing fine-grained control over security and feature policies.
• Defined new interfaces and enums (ICoreWebView2StagingProfile3, ICoreWebView2StagingTrustedOriginFeatureSetting, and COREWEBVIEW2_TRUSTED_ORIGIN_FEATURE) to represent origin-specific feature configurations, including AccentColor, PersistentStorage, and EnhancedSecurityMode.

Usage Examples and API Details:

• Provided C++ and .NET/WinRT code samples demonstrating how to set and get trusted origin feature settings, including support for wildcard origin patterns.
• Documented API details for both C++ and .NET/WinRT, specifying method signatures and usage for managing trusted origin features.

Background and Motivation:

• Explained the need for Trusted Origin support, highlighting challenges with uniform security policies and the benefits of selective feature enable
