Add HEIF/AVIF EXIF metadata extraction and UI support (#44466)

- Support EXIF extraction from HEIF/HEIC and AVIF images by detecting
container format and using correct WIC metadata paths.
- Extend supported file extensions to include .heic, .heif, and .avif.
- Add unit tests and test data for HEIF/AVIF extraction, with graceful
handling if required Windows Store extensions are missing.
- Update PowerRename settings UI to show HEIF/AVIF extension status and
provide install buttons.
- Extend ViewModel to detect/install required extensions and expose
status for binding.
