Re: [csswg-drafts] [css-values] Retiring support for 3-valued positions (excluding background)

The Blink use counter excludes syntaxes that have an offset immediately after "center". The counter is only for 3-value syntaxes that match the \<bg-position\> syntax,

```
[ center | [ left | right ] <length-percentage>? ] &&
[ center | [ top | bottom ] <length-percentage>? ]

```

The logic is essentially as follows: The first value is an identifier. Exactly one of the next two values is an identifier, the other is a \<length-percentage\>. If the second value is an identifier, it is not "center". Otherwise, the first value is not "center". "left" | "right" appear at most once. "top" | "bottom" appear at most once.
