Update Hover Text Magnifier to v1.3.3 (#4472)

- add shell32 linkage for CommandLineToArgvW
- pass immutable UIA request snapshots instead of reading live settings from the UIA thread
- reject stale UIA results by sequence, point, settings generation, and age
- remove the unload-time worker detach path and join the worker to avoid unloading the DLL under a live thread
- reduce repeated magnifier filter setup and non-erasing repaint invalidation
