Move to Uno 5.2

This fucking sucks in so many ways but I cant stick to 5.1 forever.
Here's what I've encountered:

- VS saying I have -16 projects.
- VS not loading properties
- Frames being incredbily broken on android
- WASM causing issues during android builds
- Scrollviewers and contentdialogs being a nightmare to work together
