[csswg-drafts] [css-env] border radius (#6259)

mantou132 has just created a new issue for https://github.com/w3c/csswg-drafts:

== [css-env] border radius ==
In some operating systems (such as macOS), the browser has a rounded corner of the border. When the page content sets the border, need to adapt this rounded corner

# Proposal

Add `safe-border-top-left-radius`, `safe-border-top-right-radius`, `safe-border-bottom-right-radius`, `safe-border-bottom-left-radius`  environment variables.

# Example

```css
body {
  border: 10px solid red;
  border-bottom-left-radius: env(safe-border-bottom-left-radius, 0);
  border-bottom-right-radius: env(safe-border-bottom-right-radius, 0);
}
```

current case:
