This PR fixes an issue where order-last doesn't work as expected in Firefox.

The implementation of order-last, looks like this:

.order-last {
  order: calc(infinity);
}

Which is valid CSS, and calc(infinity) is even valid in Firefox. You can use this in other properties such as border-radius:

.rounded-full {
  border-radius: calc(infinity * 1px);
}

While this works, in properties like order it just doesn't work.

Fixes: #16165

The `calc(infinity)` is supposed to work in Firefox, and it does in
places like `rounded-full` which generate:
```css
.rounded-full {
  border-radius: calc(infinity * 1px);
}
```

But in places for `order`, it doesn't complain and is valid, yet it just
doesn't work.

The order-first/last utilities were changed to use `9999` instead of
infinity because of FF:
