Re: [csswg-drafts] [mediaqueries-5] prefers-contrast: high media feature does not accurately describe the macOS/iOS state (#2943)

`true high contrast` mode, as MS does it, is forcing colors, often but not always to high contrast (it can be used to force low contrast, or any color scheme you want). This is primarily meant to be addressed through the `forced-colors` MQ together with [forced colors mode](https://drafts.csswg.org/css-color-adjust-1/#forced-colors-mode), though it does also trigger the `prefers-contrast: high` if the forced colors are indeed a high contrast set rather than low contrast one.

`prefers-contrast: high` alone, as I understand it, is more meant to reflect something along the lines of macOS's Enhanced Contrast.

Is there a situation where we have higher contrast than macOS's enhanced contrast, yet not have forced colors? If yes, it may be worth distinguishing between `prefers-contrast: increase` and `prefers-contrast: high`, but I have a bit of a hard time figuring what it is. If there isn't, what is the benefit of introducing the two levels on the `prefers-contrast` MQ in addition to having the `forced-colors` MQ?
