API Review: Origin Configuration API

[chetanpandey1266]

This pull request introduces a new specification for origin configuration 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 origin configurations and configuring feature access and security settings per origin, addressing previous limitations around uniform policy enforcement.

Origin Configuration API and Feature Management:

• Added APIs to CoreWebView2Profile for creating, setting, and retrieving feature settings for origin configurations, allowing fine-grained control over security and feature policies.
• Defined new interfaces and enums (ICoreWebView2StagingProfile3, ICoreWebView2StagingOriginConfigurationFeatureSetting, and COREWEBVIEW2_ORIGIN_CONFIGURATION_FEATURE) to represent origin-specific feature configurations, including AccentColor and EnhancedSecurityMode.

Usage Examples and API Details:

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

For configuring Enhanced Security Mode globally, the API is in discussion and might change. Will update this document based on that
