Enable Vintage Opacity (#11180)
## Summary of the Pull Request
![603-final](https://user-images.githubusercontent.com/18356694/132585665-afed3210-257a-4fee-9b43-4273a0f5cf69.gif)

Adds support for vintage style opacity, on Windows 11+. The API we're using for this exists since the time immemorial, but there's a bug in XAML Islands that prevents it from working right until Windows 11 (which we're working on backporting).

Replaces the `acrylicOpacity` setting with `opacity`, which is a uint between 0 and 100 (inclusive), default to 100.

`useAcrylic` now controls whether acrylic is used or not. Setting an opacity < 100 with `"useAcrylic": false` will use vintage style opacity.

Mouse wheeling adjusts opacity. Whether acrylic is used or not is dependent upon `useAcrylic`.

`opacity` will stealthily default to 50 if `useAcrylic:true` is set.

## Detailed Description of the Pull Request / Additional comments

Opacity was moved to AppearanceConfig. In the future, I have a mind to allow unfocused acrylic, so that'll be important then.
