Update to MUX 2.7 (#11240)

* this is the same thing as #10996, but with the fix that caused us to #11031  
* This includes https://github.com/microsoft/microsoft-ui-xaml/pull/3769, so we had to make some adjustments to how we handle tab colors. It works the same as before.
* Should enable #11231 to be started
* [x] Closes #10508
* [x] Closes #7133
* [x] Closes #8948
* [ ] I need to finish letting my 19H1 VM boot to make sure unpackaged still works
