Re: [whatwg/dom] Add builtin method to calulate line wrapping (Issue #1472)

Jamesernator left a comment (whatwg/dom#1472)

As described `.getWrappingColumns` is probably not that well defined when you take into account things like floats, whitespace collapsing around line endings, position absolute/fixed etc, slots, and probably a bunch of other CSS features that might result in boxes being unrelated to line wrapping.

Though given [`.getClientRects()`](https://developer.mozilla.org/en-US/docs/Web/API/Element/getClientRects) exists, it seems like there could just be a version of that API that gives back rects with their associated ranges and box kind. i.e. Something like:

```ts
interface Fragment {
    boxKind: "line" | "block" | "etc";
    // A line box might? consist of multiple ranges if there's an element removed from
    // the line flow in the middle of the line (e.g. a float)
    ranges: Array<StaticRange>;
    // Same as from getClientRect
    rect: DOMRect;
}

interface Element {
    getClientFragments(): { boxKind: "line" | "", rect: DOMRect }[]
}
```

This should probably be an issue in the [CSSWG](https://github.com/w3c/csswg-drafts/issues) though as this spec is purely for DOM-tree operations.
