Callum Law 831e471444 LibWeb: Support top-level tree counting functions
Adds support for `sibling-index()` and `sibling-count()` when parsing
`<number>` and `<integer>`. This is achieved by a new
`TreeCountingFunctionStyleValue` class which is converted within
`absolutized` to `NumberStyleValue` and `IntegerStyleValue` respectively

There are still a few kinks to work out in order to support these
everywhere, namely:
 - There are some `StyleValue`s which aren't absolutized (i.e. those
   which are stored within another `StyleValue` without an
   `absolutize()` method.
 - We don't have a way to represent this new `StyleValue` within
   `{Number,Integer}OrCalculated`. This would be fixed if we were to
   instead just use the `StyleValue` classes until style computation at
   which time they would be absolutized into their respective
   primitives (double, i64, etc) bypassing the need for *OrCalculated
   entirely.
