Fix missing and incorrect AccessibilityInfo types (#56708)

Summary:
Pull Request resolved: #56708

**Context**

Claude-driven audit of Flow source code vs existing public TypeScript API (manual).

**Changes**

Alignments to the `AccessibilityInfo` module for both the source Flow types and manual TS types:

- **Flow**: Move `grayscaleChanged` and `invertColorsChanged` into shared `AccessibilityEventDefinitions` — both events are registered on both platforms in the `EventNames` map.
- **TS**: Add missing event types (`accessibilityServiceChanged`, `announcementFinished`, `darkerSystemColorsChanged`, `highTextContrastChanged`, `windowStateChange`) and platform-specific JSDoc to `AccessibilityChangeEventName` members.

Changelog:
[General][Fixed] - Fix missing and incorrect types in `AccessibilityInfo` TypeScript definitions
