Pull request overview
This PR introduces a new API review spec to extend the existing WebView2 ContextMenuRequested customization flow with spellcheck support, enabling hosts that render custom context menus to surface and apply spellcheck suggestions.
Changes:
- Adds a new spec describing custom-context-menu spellcheck scenarios and motivation.
- Provides Win32 C++ and C# example flows for querying suggestions, handling async readiness, and applying a suggestion.
- Proposes new Win32 COM interfaces (
ICoreWebView2ContextMenuTarget2,ICoreWebView2ContextMenuRequestedEventArgs2) plus corresponding .NET/WinRT projections.

SpellCheck Suggestions for Custom Context Menus
Enables host apps rendering custom context menus to asynchronously retrieve and apply spellcheck suggestions for misspelled words in editable fields.
New Interfaces:
ICoreWebView2ContextMenuRequestedEventArgs2 extends ICoreWebView2ContextMenuRequestedEventArgs
ICoreWebView2GetSpellCheckSuggestionsCompletedHandler
Usage flow:
No synchronous readiness query, the single async call covers both immediate and deferred resolution.
