Add ZoomIt panoramic screenshot functionality (#46506)

<!-- Enter a brief description/summary of your PR here. What does it
fix/what does it change/how was it tested (even manually, if necessary)?
-->
## Summary of the Pull Request
This adds several ZoomIt features:

- Panorama / scrolling screenshots. The image reconstruction happens
based on visual cues and accuracy depends on scroll speed during the
capture.
- Text extraction when snipping.
- Break timer improvements (the break timer is now a screen saver,
offering the possibility to lock the computer).
- Functionality for standalone clip trimming is present but not exposed
in the XAML UI.
