[csswg-drafts] env(viewport-segment-width/height ...) should provide RTL and BTT counting mechanisms. (#11141)

Zhang-Junzhi has just created a new issue for https://github.com/w3c/csswg-drafts:

== env(viewport-segment-width/height ...) should provide RTL and BTT counting mechanisms. ==
Currently, `env(viewport-segment-width/height ...)` can only be counted left-to-right and top-to-bottom.

For example, it's easy to target the second leftmost viewport segment:

```
@media (horizontal-viewport-segments >= 2)
{
  .example1
  {
    width: env(viewport-segment-width 1 0);
  }
}
```

Targeting the second topmost works similarly.

But there's no logically equivalent way to target the second rightmost/bottommost viewport segment.

The spec need to functionally support the logical symmetry.

I suggest that negative numbers counting from right-to-left and bottom-to-top is an easy way to provide the feature.
